Using 1 or less for the "limit" may not yield the result you expect. I'm using PHP 4.1.2 I had surprising results when using explode() or split() with a "limit" of 0 or 1: in this case the returned array contains one entry with the full "remaining" string. Ex: $a = explode("/", "a/b/c", 1); var_dump($a); => array(1) { [0]=> string(5) "a/b/c" } $a = explode("/", "a/b/c", 2); var_dump($a); => array(2) { [0]=> string(1) "a" [1]=> string(3) "b/c" } Using limit=0 behaves as in limit=1 above. It seems the implementation uses limit as the number of elements to return, including the "remaining string", whereas the doc seems to describe it as indicating the number of separators to process (i.e. the resulting array should contain limit+1 entries). ---- Manual Page -- http://www.php.net/manual/en/function.explode.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+34009 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+34009&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+34009&report=yes
