I committed something similar. From docs/CODING_STANDARDS:

---------------------------
[15] Regular Expression Use
===========================

Always use the preg_* functions if possible instead of ereg_* (and
preg_split() instead of split()); they are included in PHP by default
and much more efficient and much faster than ereg_*.

NEVER use a regular expression to match or replace a static string.
explode() (in place of split()), str_replace(), strstr(), or strtr()
do the job much more efficiently.
