note 73138 added to ref.array

I couldn't get the previous set pointer functions working for whatever reason so I modifed. I trigger errors if needed but obviously you can do whatever // setPointer - Sets the pointer to the provided $key in provided $array final private function setPointer(&$array, $set_key) { // Check if $array is an array if (!is_array($array)) { trigger_error('$array must be an array', E_USER_ERROR); } // Check if $key is in $array if (!array_key_exists($set_key, $array)) { trigger_error('$set_key must exist in $array', E_USER_ERROR); } // Set array pointer to first element reset($array); // Cycle through array while ($set_key != key($array)) { // Advance the pointer next($array); } } Try with: $array = array(); $array[0] = 'zero'; $array[1] = 'one'; $array[2] = 'two'; $array[3] = 'three'; // Set the pointer setPointer($array, 1); // Display elements echo current($array); // Outputs 'one' echo next($array); // Outputs 'two' ---- Server IP: 216.194.113.175 Probable Submitter: 71.234.177.249 ---- Manual Page -- http://www.php.net/manual/en/ref.array.php Edit -- https://master.php.net/note/edit/73138 Del: integrated -- https://master.php.net/note/delete/73138/integrated Del: useless -- https://master.php.net/note/delete/73138/useless Del: bad code -- https://master.php.net/note/delete/73138/bad+code Del: spam -- https://master.php.net/note/delete/73138/spam Del: non-english -- https://master.php.net/note/delete/73138/non-english Del: in docs -- https://master.php.net/note/delete/73138/in+docs Del: other reasons-- https://master.php.net/note/delete/73138 Reject -- https://master.php.net/note/reject/73138 Search -- https://master.php.net/manage/user-notes.php
