二维数组在PHP开发中经常遇到,但是他的排序就不如一维数组那样用内置函数来的方便了,二维数组的排序需要我们自己写函数处理了,,这里UncleToo给大家分享一个PHP二维数组排序的函数:

代码:

复制代码 代码如下:


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;
}


函数的三个参数说明:

$arr:要排序的数组

$keys:指定根据哪个键值排序

$type:排序方式,升序还是降序,默认为升序

这个PHP函数可以实现对一个二维数组根据指定键值进行排序,并返回排序后的数组。

调用示例:

复制代码 代码如下:


$newArray= array_sort($array,'price');
