big size affects file put content?

[asmith]

Hi,

 

I'm doing something like this to get some data from some files :

 

<?php
$neededData = substr(current(explode('FFFFFFFF',substr(bin2hex(file_get_contents('file.ext')),36))),0,-80);
?>

 

It works fine with small sizes, like 200kb . But when I try a file with 1.4 mb  it just fails. says nothing and fails.

 

Any idea?
