PHP: Turning multidimensional arrays to single dimension arrays

Question

Array
(
    [0] => Array
        (
                     


        

Answer 1

Consider $mArray as multidimensional array and $sArray as single dimensional array this code will ignore the parent array

function flatten_array($mArray) {
    $sArray = array();

    foreach ($mArray as $row) {
        if ( !(is_array($row)) ) {
            if($sArray[] = $row){
            }
        } else {
            $sArray = array_merge($sArray,flatten_array($row));
        }
    }
    return $sArray;
}
