note 36901 added to function.is-numeric

It's important to test for is_numeric() before empty() - if the variable is 0 is will be considered empty and never make it to the is_numeric test. i.e. $x=0; if (empty($x)) print "$x is empty"; else if (is_numeric($x)) print "$x is numeric"; You will never see "0 is numeric", only "0 is empty". This note is on the empty() page but I thought it should be noted here. ---- Manual Page -- http://www.php.net/manual/en/function.is-numeric.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+36901 Delete -- http://master.php.net/manage/user-notes.php?action=delete+36901&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+36901&report=yes Search -- http://master.php.net/manage/user-notes.php
