在require行上的preg_replace

Question

Trying to just keep the file name and remove all other characters.

require_once($GLOBALS['root'] . '/library/test/TestFactory.php');

Want it to look like this:

/library/test/TestFactory.php

So far have this

$string = "require_once($GLOBALS['root'] . '/library/test/TestFactory.php');"
$string = preg_replace("~^.*?(?=\/)~i", "", $string);

I get this but just missing the end characters of "');" Any help would be appreciated.

/library/test/TestFactory.php');

UPDATE, on another instance i get something like this but my regex won't read it well as it don't have a / in there.

require_once($_SERVER['DOCUMENT_ROOT'] . $this->config . 'display.php

I would think i would want just display.php

You can try the following for both of your cases.

$str = preg_replace('~^[^.]*\.[^\'"]*[\'"]([^\'"]+).*~m', '$1', $str);
