Question

Can somebody tell me what I am doing wrong really? I am going nuts, the following code works perfect on localhost/WIN and when I try it on the webhost/linux it gives warnings:

$lines = file('english.php'); foreach($lines as $line) {     $matches=array();     if (preg_match('/DEFINE\(\'(.*?)\',\s*\'(.*)\'\);/i', $line, $matches)) {         $keys[] = $matches[1];         $values[] = $matches[2];     } } $lang = array_combine($keys, $values); 

When I test on webhost:

Warning: array_combine() expects parameter 1 to be array, null given in /home/xx/public_html/xx on line 616 

But on local server (windows xp) it works perfect. I do not know what I am doing wrong, please help me resolve this nightmare 🙁

Thanks.

I don’t see anything obviously wrong with your code, but I’m curious why you’re building separate arrays and then combining them rather than just building a combined array:

// Make sure this file is local to the system the script is running on. // If it's a 'url://' path, you can run into url_fopen problems. $lines = file('english.php');  // No need to reinitialize each time. $matches = array();  $lang = array(); foreach($lines as $line) {     if (preg_match('/DEFINE\(\'([^\']*)\',\s*\'([^\\\\\']*(?:\\.[^\\\\\']*)*)\'\);/i', $line, $matches)) {         $lang[$matches[1]] = $matches[2];     } } 

(I’ve also changed your regex to handle single quotes.)
