How to “flatten” a multi-dimensional array to simple one in PHP?

Question

It\'s probably beginner question but I\'m going through documentation for longer time already and I can\'t find any solution. I thought I could use implode for each dimensio

Answer 1

/*consider $mArray as multidimensional array and $sArray as single dimensional array
this code will ignore the parent array
*/

function flatten_array2($mArray) {
    $sArray = array();

    foreach ($mArray as $row) {
        if ( !(is_array($row)) ) {
            if($sArray[] = $row){
            }
        } else {
            $sArray = array_merge($sArray,flatten_array2($row));
        }
    }
    return $sArray;
}
