In the PHP file, you would use the super global $_POST. This is an array of all data passed via the POST command.

在PHP文件中,您将使用超级全局$ _POST。这是通过POST命令传递的所有数据的数组。

To iterate through it, would be like

迭代它,就像

foreach($_POST as $sPostKey => $sPostValue) {

    // do stuff here

}

Remember to use json_decode to turn that JSON into something usable within PHP.

记得使用json_decode将JSON转换为PHP中可用的东西。
