I have stored procedure that I created in MySQL and want PHP to call that stored procedure. What is the best way to do this?

-MySQL client version: 4.1.11
-MySQL Server version: 5.0.45

Here is my stored procedure:

DELIMITER $$

DROP FUNCTION IF EXISTS `getNodeName` $$
CREATE FUNCTION `getTreeNodeName`(`nid` int) RETURNS varchar(25) CHARSET utf8
BEGIN
 DECLARE nodeName varchar(25);
 SELECT name into nodeName FROM tree
 WHERE id = nid;
 RETURN nodeName;
END $$

DELIMITER ;

What is the PHP code to invoke the procedure getTreeNodeName?

This is my solution with prepared statements and stored procedure is returning several rows not only one value.

<?php

require 'config.php';
header('Content-type:application/json');
$connection->set_charset('utf8');

$mIds = $_GET['ids'];

$stmt = $connection->prepare("CALL sp_takes_string_returns_table(?)");
$stmt->bind_param("s", $mIds);

$stmt->execute();

$result = $stmt->get_result();
$response = $result->fetch_all(MYSQLI_ASSOC);
echo json_encode($response);

$stmt->close();
$connection->close();
