note 119334 added to function.is-numeric

I realized my is_ipaddress function had a small bug. It would return true for an IP like "1234.12345.123456.12345678" so I changed one if condition to ensure the length of each group of numbers is less than or equal to 3. NOTE: This function does not determine if the IP is restricted for LAN or other. In other words, it will match 127.0.0.1 /* is_ipaddress($input) */ function is_ipaddress($input) { // PSpider.com -- My MOST genius function. 2016/04/29 @ 2131 EST // Updated: 2016/05/14 @ 1946 EST (stoned out of mind. slightly intoxicated) // Added to PHP.NET manual under function is_numeric() - root@pspider.com $ctra = 0; $tmpout = explode(".",$input); if (count($tmpout) == 4) { // There are four sections in the array (Ex. XXX.XXX.XXX.XXX) // Check if all elements of array are a number (Ex. 127.0.0.1) foreach ($element as $tmpout) { // Nother noob steak.... if (is_numeric($element) && (strlen(($element) <= 3)) { // The element is numeric. ++$ctra; } } // Is the count of numeric elements = 4 and each element has 3 numbers ? if ($ctra == 4) { return true; } else { return false; } } else { return false; } } ~nJoy ;) ---- Server IP: 72.52.91.14 Probable Submitter: 45.78.200.221 ---- Manual Page -- http://php.net/manual/en/function.is-numeric.php Edit -- https://master.php.net/note/edit/119334 Del: integrated -- https://master.php.net/note/delete/119334/integrated Del: useless -- https://master.php.net/note/delete/119334/useless Del: bad code -- https://master.php.net/note/delete/119334/bad+code Del: spam -- https://master.php.net/note/delete/119334/spam Del: non-english -- https://master.php.net/note/delete/119334/non-english Del: in docs -- https://master.php.net/note/delete/119334/in+docs Del: other reasons-- https://master.php.net/note/delete/119334 Reject -- https://master.php.net/note/reject/119334 Search -- https://master.php.net/manage/user-notes.php
