比较只有1数组的数组值 [英] Comparing array values of just 1 array

问题描述

下面是我的数组：

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [0] => West
                    [1] => 4
                )

            [1] => Array
                (
                    [0] => South west
                    [1] => 20
                )

        )

)

我想实现的是能够比较 $阵列[0] [0] [1] 和 $阵列[0] [ 1] [1] 。故取其较小至上，我得到的价值。因此，在这种情况下，我知道4较小，所以我得到西首，然后向西南方旁边。它应该是动态的，因为我们可以得到2个以上。

What I want to achieve is be able to compare $array[0][0][1] and $array[0][1][1]. So whichever is lesser comes first and I get the value. So in this case I know that 4 is lesser so I get West first then South west is next. It should be dynamic since we can get more than 2.

推荐答案

这一个简单的例子，你可以使用：

This a simple example you can use :

$arr = array(
array("name"=>"Bob","age"=>8,"colour"=>"red"),
array("name"=>"Greg","age"=>12,"colour"=>"blue"),
array("name"=>"Andy","age"=>5,"colour"=>"purple"));

$sortArray = array();

foreach($arr as $val){
    foreach($val as $key=>$value){
        if(!isset($sortArray[$key])){
            $sortArray[$key] = array();
        }
        $sortArray[$key][] = $value;
    }
}

$orderby = "age"; //change this to whatever key you want from the array

array_multisort($sortArray[$orderby],SORT_ASC,$arr);

print_r($arr);
