php:循环遍历 json 数组 [英] php: loop through json array

问题描述

我有一个 json 数组:

<预><代码>[{"var1": "9","var2": "16",var3":16"},{"var1": "8","var2": "15",var3":15"}]

如何使用 php 遍历这个数组?

解决方案

如果需要关联数组，请将第二个函数参数设置为 true

如果需要关联数组，某些版本的 php 需要第二个参数为 true

$json = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';$array = json_decode( $json, true );

I have a json array:

[
    {
        "var1": "9",
        "var2": "16",
        "var3": "16"
    },
    {
        "var1": "8",
        "var2": "15",
        "var3": "15"
    }
]

How can I loop through this array using php?

解决方案

Set the second function parameter to true if you require an associative array

Some versions of php require a 2nd paramter of true if you require an associative array

$json  = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';
$array = json_decode( $json, true );
