|Summary||0004686: preg_replace_callback does not return empty groups|
When running Wordpress 3.2.1 on top of Quercus there was a difference between the results I got from PHP/5.3.4 and Quercus 4.0.18.
The problam is that the implementation for preg_replace_callback (pregReplaceCallbackImpl) does not return empty groups.
When going through the Quercus source code I found the following lines commented out in pregReplaceCallbackImpl.
/* PHP's preg_replace_callback does not return empty groups
so it seems PHP's previous implementations did not return empty groups. Uncommenting the else-clause solved my problem running Wordpress on Quercus.
