How to call a MySQL stored procedure from within PHP code?

Question

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?

I now found solution by using mysqli instead of mysql.

<?php 

// enable error reporting
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
//connect to database
$connection = mysqli_connect("hostname", "user", "password", "db", "port");

//run the store proc
$result = mysqli_query($connection, "CALL StoreProcName");

//loop the result set
while ($row = mysqli_fetch_array($result)){     
  echo $row[0] . " - " . + $row[1]; 
}

I found that many people seem to have a problem with using mysql_connect, mysql_query and mysql_fetch_array.
