循环遍历字符串并在PHP中构建json数组

我从购物车请求返回了以下json字符串

[{"id":19,"name":"Memory","display_name":"Memory","type":"S","values":{"url":"https:\/\/store-v035aw9.mybigcommerce.com\/api\/v2\/options\/19\/values.json","resource":"\/options\/19\/values"}},{"id":20,"name":"Add Keyboard & Mouse","display_name":"Add Keyboard & Mouse","type":"S","values":{"url":"https:\/\/store-v035aw9.mybigcommerce.com\/api\/v2\/options\/20\/values.json","resource":"\/options\/20\/values"}},{"id":21,"name":"Monitor","display_name":"Monitor","type":"S","values":{"url":"https:\/\/store-v035aw9.mybigcommerce.com\/api\/v2\/options\/21\/values.json","resource":"\/options\/21\/values"}},{"id":22,"name":"Operating System","display_name":"Operating System","type":"S","values":{"url":"https:\/\/store-v035aw9.mybigcommerce.com\/api\/v2\/options\/22\/values.json","resource":"\/options\/22\/values"}},{"id":23,"name":"AntiVirus","display_name":"AntiVirus","type":"RB","values":{"url":"https:\/\/store-v035aw9.mybigcommerce.com\/api\/v2\/options\/23\/values.json","resource":"\/options\/23\/values"}}]

我需要循环上述内容并提取id的每个值“

然后，我为每个值调用另一个url。 这将返回一个json字符串（对于id=19）：

id=20

[{"id":75,"option_id":20,"label":"No (Default)","sort_order":0,"value":"No (Default)"},{"id":76,"option_id":20,"label":"Yes (+$18)","sort_order":1,"value":"Yes (+$18)"}]

我现在需要将所有这些结合起来，并作为一个json数组进行回显

所以问题是。 1.如何将第一个转换为数组并循环。 2.将返回的所有字符串合并到一个json数组中

如果您的PHP版本较旧，并且没有这些函数，则上述页面中的注释将引用其他实现

大约：

$inJSON = <<<EOF

到目前为止你做了什么？你搜索过谷歌或php.net吗？谢谢。我（在循环中）使用了$curlProductData=str_replace（“[”，“，$curlProductData）；$curlProductData=str_replace（“]，“，”，“，$curlProductData）；$finalString=$finalString.$curlProductData；}然后在循环外$finalString=substr\u replace（$finalString，“，-1）；$finalString='['.$finalString.']]；这给了我所需的格式。echo$finalString；@user3193843欢迎兄弟！编码快乐！
