note 67510 added to ref.math

I could not resist to do a simpler version of the ordinal function: <?php function ordinal($num) { $num = (int)$num; $digit = substr($num, -1, 1); $ord = "th"; switch($digit) { case 1: $ord = "st"; break; case 2: $ord = "nd"; break; case 3: $ord = "rd"; break; break; } return $num.$ord; } ?> One could replace the typecast with <?php if($num===NULL or $num==="") {return NULL;} ?> to get an empty result instead of "0th" in case $num is empty too. ---- Server IP: 212.124.37.9 Probable Submitter: 212.223.3.162 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/ref.math.php Edit -- http://master.php.net/note/edit/67510 Del: integrated -- http://master.php.net/note/delete/67510/integrated Del: useless -- http://master.php.net/note/delete/67510/useless Del: bad code -- http://master.php.net/note/delete/67510/bad+code Del: spam -- http://master.php.net/note/delete/67510/spam Del: non-english -- http://master.php.net/note/delete/67510/non-english Del: in docs -- http://master.php.net/note/delete/67510/in+docs Del: other reasons-- http://master.php.net/note/delete/67510 Reject -- http://master.php.net/note/reject/67510 Search -- http://master.php.net/manage/user-notes.php
