PHP 4.0 Bug #9265: passing preg_split a limit parameter of 0 supresses all matches

From: chuck@horde.org Operating system: Linux 2.2 PHP version: 4.0 Latest CVS (14/02/2001) PHP Bug Type: PCRE related Bug description: passing preg_split a limit parameter of 0 supresses all matches Somewhere in the last few weeks, preg_split changed so that specifiying a limit parameter of 0 returns the string to be split unchanged. Before that, 0 was seemingly treated as no limit, meaning that you could safely specify 0 as the limit argument in order to specify a flag as the fourth argument. <?php $foo = 'a|b|c|d'; $m = preg_split('/|/', $foo, 0); var_dump($m); ?> will return everything in the same array, whereas if the limit argument is left off (or increased), the string gets split up. The behavior allowing 0 to be no limit should be returned, or another safe argument for limit that means no limit documented. -- Edit Bug report at: http://bugs.php.net/?id=9265&edit=1
