note 64442 added to function.isset

Sometimes you have to check if an array has some keys. To achieve it you can use "isset" like this: isset($array['key1'], $array['key2'], $array['key3'], $array['key4']) You have to write $array all times and it is reiterative if you use same array each time. With this simple function you can check if an array has some keys: <?php function isset_array() { if (func_num_args() < 2) return true; $args = func_get_args(); $array = array_shift($args); if (!is_array($array)) return false; foreach ($args as $n) if (!isset($array[$n])) return false; return true; } ?> Use: isset_array($array, 'key1', 'key2', 'key3', 'key4') First parameter has the array; following parameters has the keys you want to check. ---- Server IP: 130.206.1.5 Probable Submitter: 81.202.114.192 ---- 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/function.isset.php Edit -- http://master.php.net/note/edit/64442 Del: integrated -- http://master.php.net/note/delete/64442/integrated Del: useless -- http://master.php.net/note/delete/64442/useless Del: bad code -- http://master.php.net/note/delete/64442/bad+code Del: spam -- http://master.php.net/note/delete/64442/spam Del: non-english -- http://master.php.net/note/delete/64442/non-english Del: in docs -- http://master.php.net/note/delete/64442/in+docs Del: other reasons-- http://master.php.net/note/delete/64442 Reject -- http://master.php.net/note/reject/64442 Search -- http://master.php.net/manage/user-notes.php
