The sorting of two-dimensional arrays requires us to write our own functions. Here UncleToo shares a PHP with you Two-dimensional array sorting function:

functionarray_sort($arr,$keys,$type='asc'){ 
$keysvalue= $new_array= array(); 
foreach($arras$k=>$v){ 
$keysvalue[$k] = $v[$keys]; 
} 
if($type== 'asc'){ 
asort($keysvalue); 
}else{ 
arsort($keysvalue); 
} 
reset($keysvalue); 
foreach($keysvalueas$k=>$v){ 
$new_array[$k] = $arr[$k]; 
} 
return$new_array; 
}

$arr: the array to be sorted
