This question is an exact duplicate of:
Is it possible to edit the php.ini file (or anything else) and have all the *php_log* files be merged in to a single php_log file instead of one per directory?
Clarification for those who don't actually read: scanning a directory for a file type and merging files are two VERY separate actions with very different answers. Apparently the dup reporters NEVER asked two questions about a topic ever. >__>
