All of my application is written in PHP, bar 1 script which happens to create a md5 hash which is used later via PHP scripts. Problem being they dont match up.

PERL:

#$linkTrue = 'http://www.themobilemakeover.co.uk/mobile-makeover-appointment-booking-signup.php'
md5_hex($linkTrue);

And for testing purposes i did this in PHP:

echo md5("http://www.themobilemakeover.co.uk/mobile-makeover-appointment-booking-signup.php");

both return different values. Does anyone know why this is?

EDIT:
WHOLE PHP SCRIPT

<?php

echo md5("http://www.themobilemakeover.co.uk/mobile-makeover-appointment-booking-signup.php");

?>

I believe its on line 274. The code might be messy but its my first script with perl, only been at it a week.

thing i got it. $dbh->quote() adds single quotes around the value.

When I try it, both programs return a4cbeef10b3c6d44ca30d96370619eef

I have the feeling you’re not giving us the whole picture. Show us the code leading up to this. In particular, check for newlines. Have you used chomp in the perl script?

Try for yourself. Here is the complete php script I used:

<?php
echo md5("http://www.themobilemakeover.co.uk/mobile-makeover-appointment-booking-signup.php");
?>

And here is a complete perl script I used:

#!/usr/bin/perl
use Digest::Perl::MD5 'md5_hex';

$linkTrue = 'http://www.themobilemakeover.co.uk/mobile-makeover-appointment-booking-signup.php';
print md5_hex($linkTrue);

edit:

Which if the two scripts is not returning that value for md5? That’s the one that has a bug. Log the value that you’re passing to md5, (with ‘[‘ before and ‘]’ after to detect extra whitespace). Does that value match what you expect?

edit 2:

It looks like you found it, right? It’s the single quotes. This:

print md5_hex("'http://www.themobilemakeover.co.uk/mobile-makeover-appointment-booking-signup.php'");

Notice the extra quotes. The above line gives me: 486c944b10ef539aa7ba4bfe607861f2
