Bug Type: Bug
Bug description:preg_replace_callback doesn't work with the "*?" (lazy
quantification)
Description:
------------
See the script below, if the $data is too big, then the script will be
failed, but if the regular expression from:
<pre>
!<script>([\s\S]*?)</script>!i
</pre>
changed to
</pre>
!<script>([\s\S]*)</script>!i
<pre>
Then, it works.
Test script:
---------------
<?php
$data = 'blabla <script>' . str_repeat("a", 1024 * 100) . '</script>';
$data = preg_replace_callback('!<script>([\s\S]*?)</script>!i',
function($matches) {
return $matches[1];
}, $data);
echo strlen($data);
?>
Expected result:
----------------
102407
Actual result:
--------------
