通过Jquery AJAX调用PHP发送JSON

I am trying to pass a JSON array from jquery ajax call to a php file and in php file, I am writing the received data to a file. My code :

我试图将JSON数组从jquery ajax调用传递给php文件,在php文件中,我将收到的数据写入文件。我的代码:

var contacts = [{"address":[],"phone":[],"last_name":"abc","email":[{"address":"[e-mail]","type":null,"selected":true}],"first_name":"Test"}];
    $.ajax({
    url: 'handler.php',
    type: "POST",
    dataType: 'json',
    data:  { 'json': JSON.stringify(contacts) } ,
    success: function(response){
        alert(response);
    }
});

And php code :

和PHP代码:

$json = $_POST['json'];
    $response = json_decode($json);

$file = fopen('test.txt','w+');
    fwrite($file, $response);
    fclose($file);

echo "Done";

It is not writing the json data into the file i.e. File is empty

它不是将json数据写入文件,即File为空

json_decode takes a JSON string, and parses it into an object (or associative array). Since you want to write it to a file, you don't need to parse it first (one writes strings to files, not objects).

json_decode接受一个JSON字符串,并将其解析为一个对象(或关联数组)。由于您要将其写入文件,因此您无需先解析它(一个将字符串写入文件,而不是对象)。

$json = $_POST['json'];
file_put_contents('text.txt', $json)
