note 126368 added to function.preg-match-all

preg_match_all() and other preg_*() functions doesn't work well with very long strings, at least longer that 1Mb. In this case case function returns FALSE and $matchers value is unpredictable, may contain some values, may be empty. In this case workaround is pre-split long string onto parts, for instance explode() long string by some criteria and then apply preg_match_all() on each part. Typical scenario for this case is log analysis by regular expressions.
