note 60118 added to function.strcspn

this function can be used like strspn(), except while that can be used to compare a string with an allowed pattern, this one can be use to compare a string with a FORBIDDEN pattern so, to know if any forbidden character has a position inside our string, we can use (not tested with backslashes)... <?php // LARGE VERSION $forbidden="\"\\?*:/@|<>"; if (strlen($filename) != strcspn($filename,$forbidden)) { echo "you cant create a file with that name!"; } // SHORT VERSION if (strlen($filename) - strcspn($filename,"\"\\?*:/@|<>")) { echo "i told you, you cant create that file"; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.strcspn.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60118 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60118&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60118&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60118&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60118&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60118&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60118&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60118&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60118&report=yes Search -- http://master.php.net/manage/user-notes.php
