note 74171 added to function.array-keys

If you want to remove a value from an array, then there is no direct mechanism. The following function uses the array_keys() function to find the key(s) of the value that you want to remove and then removes the elements for that key. I've also given some examples and the output. <?php /** * array array_remove ( array input, mixed search_value [, bool strict] ) **/ function array_remove(array &$a_Input, $m_SearchValue, $b_Strict = False) { $a_Keys = array_keys($a_Input, $m_SearchValue, $b_Strict); foreach($a_Keys as $s_Key) { unset($a_Input[$s_Key]); } return $a_Input; } ?> Beside scalar variables (integers, floats, strings, boolean), you can also use arrays as the values you want to remove. <?php // Results in array(8, 8.0, '8', '8.0') array_remove(array(8, 8.0, '8', '8.0', array(8), array('8')), array(8)); // Results in array(8, 8.0, '8', '8.0', array('8')) array_remove(array(8, 8.0, '8', '8.0', array(8), array('8')), array(8), True); ?> ---- Server IP: 87.124.64.96 Probable Submitter: 83.104.121.66 (proxied: 1.1 BANDMAIL) ---- Manual Page -- http://www.php.net/manual/en/function.array-keys.php Edit -- https://master.php.net/note/edit/74171 Del: integrated -- https://master.php.net/note/delete/74171/integrated Del: useless -- https://master.php.net/note/delete/74171/useless Del: bad code -- https://master.php.net/note/delete/74171/bad+code Del: spam -- https://master.php.net/note/delete/74171/spam Del: non-english -- https://master.php.net/note/delete/74171/non-english Del: in docs -- https://master.php.net/note/delete/74171/in+docs Del: other reasons-- https://master.php.net/note/delete/74171 Reject -- https://master.php.net/note/reject/74171 Search -- https://master.php.net/manage/user-notes.php
