$array1 = array(
0=>array(‘id‘=>8,‘name‘=>‘Apple‘,‘age‘=> 18),
1=>array(‘id‘=>8,‘name‘=>‘Bed‘,‘age‘=>17),
2=>array(‘id‘=>5,‘name‘=>‘Cos‘,‘age‘=>16),
3=>array(‘id‘=>5,‘name‘=>‘Cos‘,‘age‘=>14)
);
function sortArrByManyField(){
$args = func_get_args(); // 获取函数的参数的数组
if(empty($args)){
return null;
}
$arr = array_shift($args);
if(!is_array($arr)){
throw new Exception("第一个参数不为数组");
}
foreach($args as $key => $field){
if(is_string($field)){
$temp = array();
foreach($arr as $index=> $val){
$temp[$index] = $val[$field];
}
$args[$key] = $temp;
}
}
$args[] = &$arr;//引用值
call_user_func_array(‘array_multisort‘,$args);
return array_pop($args);
}
$arr = sortArrByManyField($array1,‘id‘,SORT_ASC,‘name‘,SORT_ASC,‘age‘,SORT_DESC);
print_r($arr);
结果如下：
array(4) {
[0]=>array(3) {
["id"]=>int(5)
["name"]=>string(3) "Cos"
["age"]=>int(16)
}
[1]=>array(3) {
["id"]=>int(5)
["name"]=>string(3) "Cos"
["age"]=>int(14)
}
[2]=>array(3) {
["id"]=>int(8)
["name"]=>string(5) "Apple"
["age"]=>int(18)
}
[3]=>array(3) {
["id"]=>int(8)
["name"]=>string(3) "Bed"
["age"]=>int(17)
}
}
PHP 数组按多个字段排序
