Question

I am using PHP as server side coding, and i want a set of values to be send to the server(in array format). how can i send that, and retrieve that array value at backend?

Answer 1

Encode it as a JSON string and decode it using PHP json_decode

• Use JSON.stringify (the source is available here) to convert your array to string at JavaScript end.
• Send this string to your PHP page using an XMLHttpRequest.
• In the PHP code, read the string from the $_POST variable and call json_encode on it.
