Wampserver不带有正则表达式的php代码

Question

Editing the whole question as i managed to narrow it down. This is the code

<?php
set_time_limit(0);
$file = file_get_contents("oui.txt");
preg_match_all("/[0-9ABCDEF]{6}(?=(?:.*?\s*)*CHINA)/", $file ,$out, PREG_PATTERN_ORDER);
var_dump($out);
?>

This code make wampserver 2.3 to show This webpage is not available but when i change the regex to any simpler for instance only [0-9ABCDEF]{6} in this very code, it run smoothly.

When this error ocurr the apache_error.log file says this:

[Sun Mar 30 17:36:56 2014] [notice] Parent: child process exited with status 3221225477 -- Restarting.

[Sun Mar 30 17:36:56 2014] [notice] Child 2376: Starting thread to listen on port 80.

Don't know if it have anything to do with the fact that it also shows errors when i try to access any folder;

[Sun Mar 30 17:36:30 2014] [error] [client 127.0.0.1] client denied by server configuration: C:/Apache2, referer: http://localhost/anyfolder/

I have no skype. Thank you very much

Answer 1

Your regex can be simplified with:

preg_match_all(
    "/[0-9ABCDEF]{6}(?=.*CHINA)/",
    $file,
    $out,
    PREG_PATTERN_ORDER|PCRE_DOTALL
);

If preg_match entered some weird loop, this should solve the issue.

The PCRE_DOTALL makes the . aware of linebreaks as well.
