Converting PHP Database Result Arrays to JSON

You want to convert the result array of a database query to JSON format in PHP. The following code retrieves a row from the database:

$row = mysql_fetch_array($result);

To convert the $row array to JSON format for use with jQuery plugins, you can utilize the json_encode function:

echo json_encode($row);

Note that json_encode is only available in PHP version 5.2.0 and above. If you are using an earlier PHP version, you may need to use a third-party library or write your own JSON encoding function.
