$arr1 = [

	['id'=>10086,'name'=>'移动'],

	['id'=>10010,'name'=>'联通'],

	['id'=>10000,'name'=>'电信'],

	['id'=>110,'name'=>'公安局'],

	['id'=>119,'name'=>'消防局'],

	['id'=>120,'name'=>'急救'],

];



$arr2 = [120,119,110,10010];



foreach($arr1 as $v){

	if(($pos = array_search($v['id'], $arr2))!== false){

		$arr3[$pos][] = $v;

	}else{

		$arr3[count($arr2)+1][] = $v;

	}

}



ksort($arr3);

$arr = [];

foreach($arr3 as $v){

	$arr = array_merge($arr, array_values($v));

}

print_r($arr3);

print_r($arr);

最后输出如下（按照$arr2排序）：
