It's because array_search searches your array for the string 'Partners'. But as your array only contains 3 arrays, no entry is found. array_search will result false which evaluates to 0. That's why the first key is removed.

You need to search inside each array (foreach ($myarray as $array) { ... }). And you also must check the return value:

$value = array_search(...); if ($value !== false) { // do unset } 

Solution with array_filter:

// Remove all arrays having 'title' => 'Partners' $arr = array_filter($arr, function($e) { return $e['title'] != 'Partners'; }); // Remove all arrays containing a value 'Partners' $arr = array_filter($arr, function($e) { return array_search('Partners', $e) === false; });
