To my great embarassment. Came away with a copy of PHP5 &
MySQL Bible thinking to do a couple of hours study
every day of my hols with a view to learning a little
elementary PHP to assist me with my CMS website work.
Read through the first couple of Chapters until I came to
Chapter 4 and 'Your First PHP Program 'Hello World'' in
which I am instructed to type
<HTML>
<HEAD>
<TITLE>My first PHP program</TITLE>
</HEAD>
<BODY>
<?php
print(“Hello, cruel world<BR><BR>\n”);
phpinfo();
?>
</BODY>
</HTML>
Saved as .html and viewed with Wampserver I got nothing
but
\n”); phpinfo(); ?>
on the resulting page. Copied and pasted in case of
typos, same result. Installed EasyPHP and got the same
result. Uploaded file to webserver and viewed it on the
web:
\n”); phpinfo(); ?>
on its own and nothing but.
Humph. So, Help please.

AFAIK all php programs MUST start with <?php even if they are
immediately reverted to text with ?>
So try
<?php ?>
as the first line.

To people who know too much, it is a sad fact
that they know how little is really possible -
and how hard it is to achieve it.

No. It's even legal for a PHP file to contain HTML only (without any
<?php ...?>).
But to be processed as PHP the webserver has to know, that it's a PHP
file. This is typically done by saving the file as *.php instead of *.html

Really? I must try that..
I have to say I never bothered to write a php file that didn't start
with <?php

This double qoutes you are using... Looks like the type of quotes that
some word processors like "Microsoft word" uses... And are not valid
characters.
“ And ” are not the same that "
Perhaps the PHP is doing and error and you have the error display
disabled.
if the file extension is .html can be that the file is not processed
bye the PHP and delivered as is to the browser. Then, you can look the
source code through the browser And see the php on it.
Try using .php as the file extension. Try also using the correct double
quote character.
Regards

As Shake already pointed out, the “ and ” ain't the same as " and you
should use a text editor instead of an office application to edit your
php scripts.
As you seems to be a microsoft user, I suggest you download and install
notepad++ and you find their homepage at http://notepad-plus-plus.org
> Saved as .html and viewed with Wampserver I got nothing
This will tell your Apache that the file will be an html file and it
will not be parsed by the php engine (contrary to what The Natural
Philosopher wrote). You need to either reconfigure your Apache to handle
all .html files as php scripts (this will mean all files ending with
..html will be parsed by the php engine and give overhead for your
computer if you are serving plain html files), the best solution is to
name the file to end with .php and the file will be parsed by the php
engine.
> but
>
> \n”); phpinfo(); ?>
This for your script file isn't a plain html file, so it will try it's
best to understand your HTML and present what you wrote, if you would
choose to look at the source of the HTML page in your browser, you will
see it's exactly the same as what you wrote in your file.

It works, you were correct on both errors. My book is in pdf so I had copied and pasted directly from the text into notepad++ thinking it was sure to be correct,lol. And the extension I had as .html, so thank you, I can continue my learning now.

Those typographical double quotes characters are valid (they are defined in
Unicode, after all), but the (PHP) source code is not, because they are not
string literal delimiters (in PHP).

Mmmm, no. If f'rinstance you're running it as a CLI script you'd prolly
want it to start:
#!/usr/bin/php
<?php
etc.
If OTOH you have it as a script for apache to run, it doesn't matter.
You can start with plain text, which will just be sent to the browser.
Any <?php ?> blocks are interpreted and any output they produce will be
sent to the browser. You can as many such blocks as you like with text
in between, or none at all. Or put everything inside one such block.

You don't even *have* to use a .php suffix, either. You could use .shit
if you wanted to. But you'd have to configure apache or whatever to
recognise that scripts whose names end in .shit have PHP in them, to be
interpreted please.
The only reason that .php typically works is because the default config
for apache contains the necessary configuration commands for having the
..php work as you'd expect. If you remove that, however, it won't
recognise *any* file as having PHP in it, to be interpreted please.
I use .phtml, personally.

You would have thought that was the default... :-)

No - this is not neccessary and no it does not make the webserver
believe it should forward HTML files to PHP. See above - the extension
is the key - ".php" and not ".html".
