中提取了以下JSON

我想要做的是在PHP中编写一个函数，它将最近的目标邮政编码返回到源地址。所以它应该返回94536。

已经花了大约4个小时，而且这里的格式运气不好:)。 Ty提前。

这是我目前在代码点火器功能

中所拥有的

<?php

已定义（'BASEPATH'）或退出（'不允许直接访问脚本'）;

public function index()

    $json = file_get_contents('https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=89706&destinations=94536|73301|61462&key=AIzaSyBQu1UgozO7yjQzYtvZkB05RI-5E6Qo5DU');
    $jsondecoded = json_decode($json);

    //testing to get first zip code just to make sure we can get zip code only (Not needed here)
        $matches = [];
        preg_match("#.*?(\d+)#", json_decode($json, true)['destination_addresses'][0], $matches);
        echo $matches[1];

    // just a test to see that the complete json is there. (Not needed here just for testing)
    echo '<hr>';
        echo '<pre>';
            print_r($jsondecoded);
        echo '</pre>';
    echo '<hr>';

    // looping though elements tryign to order the distance text by closest first   (lost here but still testing)
    foreach ($jsondecoded->rows as $element) {
        echo '<pre>';
            print_r($element);
        echo '</pre>';
        echo '<hr>';
    }

    // I need to build a function that find the closest destination_addresses zip code and return it. So i would need to sort the rows->elements->distance->text / value by the closest adn then match that to correct destination_addresses

你只需要解码json让我们说它将在$ json变量中并使用简单的正则表达式，其中\d代表数字

$json = ''; //your json from curl or any other way
$matches = [];

preg_match("#.*?(\d+)#", json_decode($json, true)['destination_addresses'][0], $matches);

echo $matches[1]; // your adress

如果json响应包含数组键等，可能需要添加一些检查。
