Get Posted Json Array In Php

How can I send a POST request along with a JSON array to main.php to return the value of key_1? My current method below doesn't work and I can't figure out how to fix this. script.

Solution 1:

file_get_contents() does not parse the content. You need to pass the value through json_decode().

<?php$params = json_decode(file_get_contents("php://input"), true);
    echo ($params["key_1"]);
?>

Solution 2:

In main.php, use this code:

<?php$params = json_decode(file_get_contents("php://input"));
    echo$params->key_1;
?>

When you decode a JSON string, you convert it to an object of stdClass.

If you want to decode JSON and convert it to an array, use code below:

<?php$params = json_decode(file_get_contents("php://input"), true);
    echo$params['key_1'];
?>
