note 71637 added to function.explode

The following function compares two ip-adresses. On match it returns true, otherwise false. <?php function compare_ip($ipreg,$ip) { $ipreg = explode('.',$ipreg); $ip = explode('.',$ip); for ($i = 0; $i < 4; $i++) { if ($ipreg[$i] != $ip[$i] && $ipreg[$i] != '*') return false; } return true; } ?> Examples: <?php var_dump(compare_ip('123.121.144.1','123.121.144.2')); // false var_dump(compare_ip('123.121.144.1','123.121.144.1')); // true var_dump(compare_ip('123.121.144.*','123.121.144.23')); // true var_dump(compare_ip('123.121.*.*','123.121.2.4')); // true ?> Have fun :) ---- Server IP: 194.153.94.10 Probable Submitter: 80.219.154.129 ---- Manual Page -- http://www.php.net/manual/en/function.explode.php Edit -- https://master.php.net/note/edit/71637 Del: integrated -- https://master.php.net/note/delete/71637/integrated Del: useless -- https://master.php.net/note/delete/71637/useless Del: bad code -- https://master.php.net/note/delete/71637/bad+code Del: spam -- https://master.php.net/note/delete/71637/spam Del: non-english -- https://master.php.net/note/delete/71637/non-english Del: in docs -- https://master.php.net/note/delete/71637/in+docs Del: other reasons-- https://master.php.net/note/delete/71637 Reject -- https://master.php.net/note/reject/71637 Search -- https://master.php.net/manage/user-notes.php
