From manual page: http://www.php.net/reference.pcre.pattern.posix
---

the text says pcre stops at the first match.

The first match is 'one' not 'oneself'. preg_match behaves as described (finding 'oneself') but the text does not explain why or how to predict this behaviour. perhaps the definition of 'first' is unclear?




Test script:
---------------
preg_match('/one(self)?(selfsufficient)?/','oneselfsufficient',$r);
print_r($r);  /* behaves as described */
preg_match('/one(self)?(selfsufficient)?/','one',$r);
print_r($r);  /* one is the first match */
