$arr = Data Araay;

$fldName = Group By Colum Name;

function array_group_by( $arr, $fldName) {
    $groups = array();
    foreach ($arr as $rec) {
        $groups[$rec[$fldName]] = $rec;
    }
    return $groups;
}

function object_group_by( $obj, $fldName) {
    $groups = array();
    foreach ($obj as $rec) {
        $groups[$rec->$fldName] = $rec;
    }
    return $groups;
}
