How to pass array of values from php to JS using Ajax and json?

in your ajax call, you need to specify the data type; for example:

It is very simple to pass a PHP array to JS using Ajax and Json. You can send an array from PHP using JSON_ENCODE function from PHP and get it using JSON_DECODE function in JS.

Here is a simple example:

JS

$.post("example.php", { user_id:10 } , function( data ){       

    alert( data.user_info.user_id );

    alert( data.user_info.user_name );

   // Do something as per your logic.}, "json");

exmple.php

<?php

$q = "SELECT * FROM users WHERE user_id = ".$_POST['user_id'];

$r = mysql_query( $q  );

$user_info = mysql_fetch_array( $r, MYSQL_ASSOC );

echo json_encode( array( "user_info" => $user_info ));

?>

Enjoy coding :) !!

Instead of using an array, you should use an object literal (~= assoc array in php).
