PHP字符串到json数组

PHP string to json array

本文关键字：数组 json 字符串 PHP      更新时间：2023-09-26

所以基本上我正在进行cURL请求并得到如下响应（var_dump）：

string(595) "{"user_id":1,"currency":"eur","purchase_packs":{"1":{"amount":500,"allowed_payment_methods":["ideal","paypal","visa","mc"]},"3":{"amount":1000,"allowed_payment_methods":["mc","ideal","paypal","visa"]},"6":{"amount":2500,"allowed_payment_methods":["mc","ideal","paypal"]},"8":{"amount":5000,"allowed_payment_methods":["ideal"]},"9":{"amount":10000,"allowed_payment_methods":["ideal"]}},"payment_methods":{"ideal":{"name":"ideal","allow_recurring":false},"paypal":{"name":"paypal","allow_recurring":false},"visa":{"name":"visa","allow_recurring":false},"mc":{"name":"mc","allow_recurring":false}}}"

我想要的是在JS文件中访问它，如下所示：

success: function (data) {
    alert(data.user_id);
}

但我不知道如何正确地转换它。

在那之后，我的下一步（问题）是，我是否可以为每个购买的包做一个for循环，这样我就可以为每个包创建按钮

可能是这样的：

var pack;
var packs = data.purchase_packs;
for (pack= 0; pack < packs.length; pack++) {
    console.log(packs[pack]);
}

我试着理解你的"问题"。。。。

js:

$.post('/some/url',{query: 'somequery'},
function (data) {
    try {
        data = JSON.parse(data);
    } catch (e) {
        return false;
    }
    console.log(data);
});

在PHP中：

data = json_decode(rtrim($myJSONEncodedString, "'0"));
if (!empty($data->purchase_packs)
    foreach ($data->purchase_packs as $key => $value)
        var_dump($value);

使用cURL收到响应后，只需在<script></script>标记之间回显json字符串。

然后json字符串将看起来像：

<script>
var jsondata = {"user_id":1,"currency":"eur","purchase_packs":{"1":{"amount":500,"allowed_payment_methods":["ideal","paypal","visa","mc"]},"3":{"amount":1000,"allowed_payment_methods":["mc","ideal","paypal","visa"]},"6":{"amount":2500,"allowed_payment_methods":["mc","ideal","paypal"]},"8":{"amount":5000,"allowed_payment_methods":["ideal"]},"9":{"amount":10000,"allowed_payment_methods":["ideal"]}},"payment_methods":{"ideal":{"name":"ideal","allow_recurring":false},"paypal":{"name":"paypal","allow_recurring":false},"visa":{"name":"visa","allow_recurring":false},"mc":{"name":"mc","allow_recurring":false}}};
</script>

然后，您的javascript代码在<script></script>之间。像这样：

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>
    alert(jsondata.user_id); // return user_id value
    jQuery.each(jsondata.purchase_packs, function(i, val) {   
      alert(val.amount); // return amount
      var paymentMethod = val.allowed_payment_methods;
      jQuery.each(paymentMethod, function() {
          alert(this); // will return all payment gateway method
        });     
    });
</script>

希望会有所帮助！
