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:

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
