Question

I have an array in my javascript function having string values like 1,2,3,4… etc.
I want to store this array in PHP’s session. I searched it and they say to use JSON but I am getting the way how to use JSON.

Suppose my array’s name is: myArray
and I want to do something like this: $_SESSION[‘myArray’] = myArray;

Is there anyway of doing that? Please provide some working code sample if possible.

Your JavaScript is running on the client, your PHP is running on the server. You need to send the data over HTTP.

To get data from a JavaScript array to a PHP session you need to:

1. Serialise the data (either to a collection of inputs in a form, or to a string. The JSON object can help with the latter so long as you don’t have data types that JSON doesn’t support).
2. Send the data to PHP (either by submitting a form, or using Ajax)
3. Read the data back in PHP (probably from $_POST)
4. Optionally deserialise it back to a data structure
5. Store it in $_SESSION
