To convert a JavaScript object into a JSON object in PHP, you can use the json_decode() function. This function takes a JSON encoded string and converts it into a PHP variable .
Assuming you have a JavaScript object that you want to convert into a JSON string and then convert that string into a PHP object, you can do the following:
JavaScript:
var obj = { name: 'John', age: 30, city: 'New York' };
var jsonString = JSON.stringify(obj);
PHP:
$jsonString = '{"name":"John","age":30,"city":"New York"}';
$phpObj = json_decode($jsonString);
In this example, the J avaScript object is first converted into a JSON string using the JSON.stringify() method. Then, in PHP, the resulting JSON string is passed to the json_decode() function to create a PHP object .
If you have a JavaScript object literal that is already in the form of a JSON string, you can skip the JSON.stringify() step and directly pass the string to json_decode() like this:
JavaScript:
var jsonString = '{"name":"John","age":30,"city":"New York"}';
PHP:
$jsonString = '{"name":"John","age":30,"city":"New York"}';
$phpObj = json_decode($jsonString);
In both cases, $phpObj will contain a PHP object that corresponds to the original JavaScript object.
