I've asked this question on my blog. See <http://
codeaholic.blogspot.com/2011/01/php-what-cant-or-wouldnt-you-do-in-
php.html>. No flames required. No discussion about language semantics
or implementation either (if at all possible). I just want to get an
idea of what can and can't be done with PHP at the task level.

Same here, TNP.
PHP completely fails at that task!
(I couldn't reach Zend, nor Lerdorf or Gutmans for comment!)

Appart from that, PHP does pretty much anything I expect from a
serverside language.
But Axtens is only spamming his/her blog, right?

There's got to be a way of asking this question, without getting such
high quality responses.

It normally helps if you compose the question text in a such a way that
it doesn't look like an advert for your site. Whatever, you have to
assume this is Usenet and you'll get "RTM" and "Try Google" no matter
what you ask.

'At the task level', indeed!


Look up what 'task' means.

<sigh> It's just that I've tried Google, have read all sorts of
interesting things in online manuals. I just haven't had any success
in formulating the kind of question that gets the information I'm
after.

However, thank you. Thank you for responding thoughtfully. Much
appreciated.

Okay, so would *you* phrase it, seeing as I'm so dumb? I want a list
of things that are hard to do in PHP. Can PHP do decision tables? Or
change from outputting HTML to outputting RTF by just changing one
instruction (okay, it's not fair to pit PHP against Protium but do you
get what I mean here?) Okay, one thing I know already: PHP sucks when
it comes to Unicode. Anything else?

You could also reverse the approach, and start with the question what to
expect from PHP.
This way you might find out what you can expect from PHP, and this might
give a clue about what not to expect.

Als you might define 'task'..
Because wikipedia also does not know what it is, and gives a list of 6
possible meanings (http://en.wikipedia.org/wiki/Task)

Nothing you could not bring down to your oversimplifying ("task") level of
discussion.

BTW, nobody cares about your blog. This is Usenet; post *here*, discuss
*here*.

This is not a sensible question. As pointed out, there are an infinite
number of things that are hard to do in php, just as there are an
infinite number of things that are hard to do in COBOL. Having said
that, these things that are hard to do tend to be a lot easier to do
when one knows how to do them.

For instance, I had no idea that it was hard to do Unicode in php. I
wish you had told me that before I found it so easy to do Unicode in
php, because I'd have found something even easier!

If you ask Richard or jRough, they will tell you that it is hard to do
anything in php or indeed in any other language. It tends to depend on
your point of view.

Hi Bruce,

A decision table can be build in any language, even VBscript.
PHP is very strong when it comes to array manipulation, so I'd say it is
even easier to implement decision tables in PHP than in many other
languages.

HTML --> RTF ?
I wouldn't know.
I also wonder how such a RTF would look like for complex pages with lots
of positioned elements.
But if you want a simple html-->rtf, google around a sec to see what
others have come up with so far.
First google hit:
http://www.phpclasses.org/package/1805-PHP-Create-RTF-documents-from-HTML.h tml

But be prepared to find a lot of bad scripts on the net.
So it is better to master PHP yourself. (After that you won't ask
anymore "if it is possible to convert html to rtf by changing one
instruction", because you will understand better what is involved, and
that the question is a bit silly.)

I view PHP as a versatile general purpose programming language.
Of course it is centered around http, but it isn't limited to that.
I have used PHP for batched wav-file cut/pasting based on cuepoints,
batched image manipulation, artificial intelligence, etc.

If there is one thing missing in PHP, I'd say it is its lack of
integration with the desktop. (Can be done with tck, but that is
cumbersome in my humble opinion.)

Maybe you should wonder if PHP is the right language for you based on
what PHP's strong points are, not it weaknesses.

Regards,
Erwin Moller

HTML vs. RTF? Well that's essentially a meaningless question, IMO.

Here's PHP outputting some html:

echo "<html><head></head><body><p>Hi Brucey!</body></html>";

Here's PHP outputting some RTF:

echo "Here's some RTF shit - I don't know what it looks like, sorry.";


See what I mean?

Look, I understand the problem. But you have to figure out how to pose
the question. At this point, I have no idea what sort of question you're
trying to ask. Meanwhile:

1) What languages in any have you programmed in, and to what extent?

2) Have you done any of that in PHP?

Sarcasm aside, you have to admit that *native* support of Unicode is lacking
from PHP while it has been implemented in other languages that are
frequently used on the Web. This does lead to a number of problems between
the different layers of PHP-based web applications, and with porting
applications from one server to another. BTDT.

So if the OP is referring to that fact in their unique way, it is fair to
say that "doing Unicode" is obviously *harder* to do in PHP than in some
other languages (if not impossible with regard to the language tokens),
because you have to do any necessary string conversion yourself, and you
have to stick to US-ASCII-compatible identifiers (an issue that was supposed
to be fixed with PHP 6, more than a decade after e.g. ECMAScript managed to
do it, not to mention Perl and Python):

Don't try writing device drivers in it. Don't expect to use it for
critical applications involving life-threatening situations; the
language changes too rapidly and you'll find it impossible to certify to
your insurers that it is correct. It's miserable for real-time control,
or very large-scale data handling that you want finished in an
reasonable time-frame. It's too big to run well on many embedded
controllers. It's too cryptic compared to COBOL, too verbose compared to
well-optimized perl, too slow compared to c.

I'm guessing that this doesn't answer your question, however, because it
sounds like you have something very specific in mind.

It would be easier if you explained what you want to do. Even if someone did
post a list, there would be endless discussion over whether it was valid or
not. Have you even looked at such simple places as wikipedia to get search
terms?

Most of the comparisons I've found are biased one way or another. Coming
from a background of relatively strongly typed languages such as Borland
Delphi and C, I have found both of these interpreted languages frustrating
and difficult to understand. Here are a few opinions:
http://www.thesitewizard.com/archive/phpvscgi.shtml
http://www.netconcepts.com/php-versus-perl/
http://shlang.com/php-perl-comparison.php
http://www.whenpenguinsattack.com/2006/08/08/php-vs-perl/
http://blogs.computerworld.com/15460/perl_vs_php_vs_ruby
http://www.wikivs.com/wiki/Perl_vs_PHP

It is handy to be able to include PHP within HTML. There are many sometimes
conflicting modules for Perl (such as DateTime). PHP does not seem to have
the equivalent of Strict, Warnings and Taint checking. And I found PHP file
I/O to be simpler (or more C-like):

Here is an example of straightforward and simple file I/O in PHP:
$fHTMLrawfile = "Raw.htm";
$fHTMLraw = fopen($fHTMLrawfile, 'r') or die("can't open file");
if (filesize($fHTMLrawfile) > 0)
$html = fread($fHTMLraw, filesize($fHTMLrawfile));
else
$html = 'N/A';
fclose($fHTMLraw);

A similar operation in Perl requires line by line iteration (or possibly a
lower level function, or reading into an array and then assembling the
string):
if (-e $HTMLpurefile){
open (fHTMLpure, '<', $HTMLpurefile);
my $line;
$in{$key} = "";
while( $line = <fHTMLpure> ){
$in{$key} .= $line;
}
close fHTMLpure; }

I now have a PHP script which is executed within my Perl script, but I might
consider rewriting the entire thing in PHP. Maybe it would be a good
learning experience to try a bit more than a trivial helper script in PHP,
and then I'll be able to make a more educated choice. At this point, I don't
really like either one. Maybe I should just do it in C!

Sorry if this is not exactly on topic or just presents the results of a
search, but I think it's helpful, at least for me, to have this information
on usenet.

Thanks,

Paul

Well, PHP does a decent job when you set the error level to ``E_ALL
| E_STRICT''. As for adding a taint mode, I believe there may be
third-party options, but I haven't searched extensively.

A more straightforward approach (with error checking):

<?php

$file = 'foo.dat';

if (is_readable($file)) {
if (($data = file_get_contents($file)) !== false)
$data = $data ? $data : 'N/A';
}

?>

Not necessarily that complicated, you can slurp the file into a
string.

# see: perlvar
{
open my $fh, '<', 'foo.dat' or die $!;
local $/ = undef;
my $data = <$fh>;
close $fh;
}

</OT>

Unless you feel motivated to take on the academic task of better
learning PHP, or any other language for that matter, I'd recommend
using the language with which you're most comfortable.

Well, to be honest, I don't feel comfortable with either Perl or PHP. There
just seem to be too many arcane and obscure ways to do things, such as the
undef of the line by line file read above. It took me a while to find the
explanation, and to me it seemed like a hack. I have only recently (since
September) even tried to do server side scripting, and I basically found an
old Perl mailer script that did some of what I needed, and built from there.
I have several books on Perl and PHP, and HTML and MySQL and SQLite and
JScript for that matter. Most of them are at least 5-10 years old and
(especially for HTML) they are largely obsolete.

I suppose I've been spoiled by integrated development environments like
Borland Delphi, where I have the convenience of an extensive help menu with
examples and debugger built into the same application as the editor, and
I've been able to build upon a rudimentary general knowledge of the
programming language to add functionality as I need it. I feel most
comfortable when I can understand exactly what is going on, even down to
assembly language and machine code. In fact, I use a lot of assembly
language for simple PIC projects, and a C compiler for more complex projects
such as USB devices.

I started with BASIC and Fortran around 1967, and 15 years later I was using
CP/M, Z80 code, and various forms of BASIC. In 1987 I took a course in
structured programming which featured Pascal, and I used Borland Turbo
Pascal for about a year until I switched to Turbo C, which I used heavily
for MSDOS applications, and I used dBase and Clipper for database stuff. I
didn't like C++ so I discovered Borland Delphi for Windows GUI, and after I
became used to OOP it became my language of choice. However I still use PIC
code and its C compiler, and Z80 code and a C variant for some
microcontroller products. I've also used some VBScript and JavaScript for
some things using the WSH and also in web pages, and VBA for MS Access and
other Windows applications that use it.

So, I'm very new to server-side programming, and I've just found it
difficult to learn. I suppose I'm just somewhat resisting the concept of
context based typing and the myriad of alternate ways to do the same thing,
especially using very cryptic symbols instead of the much more verbose but
more intuitive and human-readable verbosity of Delphi Pascal. I actually
prefer C to some extent, but I've come to accept Delphi as my language of
choice, especially for Windows GUI.

I know I'm rambling on, and probably I should either try recoding my fairly
simple 575 line Perl script into its PHP equivalent, just to be able to
evaluate the relative merits of each for my purposes. I've had more
experience with Perl, if you can use that term to describe my sporadic
attempts to add functionality and fix problems in a server side script with
some parts I still don't really understand.

OK, by now I could have recoded half of that script in PHP. So, thanks for
the response, and maybe I'll check back in a couple of weeks when I have
gone far enough in my attempt to make a decision as to how to proceed.

If you prefer C I'm surprised you're having trouble with PHP, which I
found to be a simplification. Personally I find declaring variables to
be a bore and waste of time, along with worrying about their types.

Nothing nicer than being able to say:

$num = (something, e.g. number of result rows from database query)

$char = "s";
if ($num==1) $char = "";
if ($num==0) $num = "no";

echo "We got " . $num . " result" . $char . "\n");


thereby producing a nice human-friendly message with a small number of
statements. Try doing that in C.

I would avoid perl just for the reason you cite: far too cryptic, and
the people on the perl ng appear to focus solely on the notion of making
their programs *more* cryptic. By contrast the PHP docs site at:

<http://www.php.net/manual/en/>

is an excellent reference source. I've purchased no books on PHP and
only occasionally asked a question here.

I started programming in 1965. During the late 90s I did none at all,
but just 11 years ago, the bloke came up to me and told me I was now the
man for the company's assets database, just being created. He gave me a
quick 30 minute talk about PHP, mySQL, and JavaScript, none of which I'd
ever used, and it was only mySQL that I'd even heard of. But, that intro
was all I needed.

So why are you, with your experience, having trouble with server-side?

Hmmm, I might replace the three statements above with:

$char = $num==1 ? "" : "s";
$num = $num==0 ? "no" : $num;

Got to make the program shorter! :-)

Hi,

I have had three "epiphanies" in my life as a PC programmer. The first
was my discovery of Turbo C, mainly because of the highest qualty of
Borland's documentation. The second was Visual Basic 5 (all previous
versions did deserve the "toy language" characterization), and the
third was PHP & JavaScript.

Personally, I tend to dislike strictly typed and static languages. I
know all the advantages they bring by providing consistency checks on
compile time, but having been a C programmer for a couple of decades,
and a vicious user of void * and the like, I am pretty used to do all
those checks by myself and to test extensively.

I also find Perl to be obscure. But PHP has a perfectly consistent
syntax, a very rich set of libraries and so far it has been up to
whatever I have needed (producing server side code and retrieving text
data). It has its quircks (but every language does).

Don't try to "approach PHP from Perl". They are two completely
different beasts, even if they are more or less designed for the same
purpose. Just think of PHP as a sort of hybrid OO/procedural language,
and everything should be easier.

PHP online manual is a finest piece of work. It describes in detail
every "official" library function and every language construct, and
there are community provided examples for most of them.

And the lack of an IDE can easily be solved by having the local help
file open alongside your text editor and just commuting from one to
another, resorting to online help when you need an example.

I haven't tried the PHP plugins fo either NetBeans or Eclipse, but if
they are half as good as they are for Java, then they should be quite
confortable to work with.

Some people complains about the many redundant libraries available in
PHP. But one can test which one best fits one's needs and simply
ignore the rest. I did "C" for twenty years, and VB 5/6 for thirteen,
and I hardly used something like one half of C's libraries and perhaps
80% of VB.

You repeat yourself; every negative you've given to PHP is incorrect as
you've already been advised. Until you know from experience, you're just
guessing. And, you've missed the two most reliable sources on the 'net for
PHP. Where you're "coming from" has almost no meaning to the question you
asked.

HTH,

PHP is mainly a server side language so anything that does direct
interaction with the client is either difficult or impossible.

Arcade games with PHP is pretty much impossible.

Unless the PHP server is in your local network printing via PHP is
impossible.

Doing remote terminals (i.e. distributed databases) without a newwork
connection is nearly impossible, (you would have to mirror your PHP
server on the remote device, and then deal with syncing when returning
to the main network, so it is very difficult).

Multimedia is not a strong suit for PHP, it can do well making PDFs
some image manipulation and other static documents but is not well
suited for video, sound or animation work. Then again if the right
client application were written to work with a PHP server then you
might have some great stuff, but that isn't just PHP then.

PHP is great for building centralized applications, one of the best
languages for scaling up to the web with data or other such
applications.

PHP is syntax is more reminiscent of C's. PHP's syntax is generally
more straightforward than Perl's.

One of the guiding principles of Perl is that "There's more than one way
to do it." This means that, while you can use obscure techniques, you
are by no means bound to use them. I very rarely use Perl, but once you
get the basic idea behind a few special variables and learn to look
through the manual efficiently, it's not so bad.

I may be mistaken, but I don't believe Perl was initially designed with
a primary focus on server-side scripting. PHP, however, was.

I've used the PHP plug-in for Eclipse here and there, although I'm not a
big IDE fan. It seems to be very good, though.

Hm, that's a new one for me. I don't think I've seen any complaints
about redundant libraries. Most of the complaints I've read about PHP's
libraries have been concerning the inconsistent naming conventions.

Very much like C.

I don't know Perl, and in light of that "enthusiastic" recommendation, I
think I'll pass.

It is excellent. Besides everything else it has great integration with
CMS. Also, it has a memory and you can recover previous editing changes
that were lost. This recovery feature has helped me on more than one
occasion.

<sigh>. I always check with the "bible" (php.net) when using many
different functions just for that reason.
