[SOLVED] Help! Code error is stumping me!

[techiefreak05]

i have a code that is SUPPOSED to check if a certain META tag is in the header of a webpage.... and guess what? it saying the meta tag isnt found!! look, heres the code:

 

<?php

$meta_tag="<META name=zwm-verifyDomain content=" . $url_token . ">";

$file = "http://" . $_GET[verify];

$string = htmlentities(file_get_contents($file));

if(preg_match('/$meta_tag/i',$string)){
echo "found string";
}else{
echo "string not found";
}
?>

 

and here is the value of $meta_tag when echoed out:

<META name=zwm-verifyDomain content=2hcal6bwu495bdazs8nlm2lpk2q92q3e7ko67g5q3ewscp7cx9pniviehrz1v9qeg9ycrz>

any ideas !?!?!

if(preg_match("/$meta_tag/i",$string)) {

adding the doubles quotes instead of the single quotes didnt work ...

Try printing out the pattern you are matching, as well as the string you are matching against.  They must match exactly.

I did tat. and they do match EXACTLY. I echoed out $string, which is the source of the webpage with the META TAG, and i echoed $meta_tag, and yeah, they do match

is there something wrong with my code? can you put variables inside preg_match() ?

[techiefreak05]

!!! I got it!!

 

You have to treat variables in preg_match() as if it was echoed... like this:

 

<?php
if(preg_match('/' . $meta_tag . '/i',$string)){
?>

 

it just came to me, i tried it. and it works!! :-)
