| Hi, To check if the value is included in mutlidimensional array, you can use the solution below. The function is calling itself to check if the value is included in sub-arrays. Please note that it is checking the array values, but not the array keys. function in_multidimensional_array($value, $multidimensional_array) { foreach ($multidimensional_array as $array_value) { if ( $array_value == $value OR ( is_array($array_value) AND in_multidimensional_array($value, $array_value) ) ) { return true; } } return false; } $arr = array(1 => array("abc","def"), 2 => array("aaa","bbb")); if ( in_multidimensional_array("aaa",$arr) ) { echo "Value is included in array."; } else { echo "Value is not included in array."; } | |||||||||||
