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.
<?php
$res = mysql_query('SELECT getTreeNodeName(1) AS result');
if ($res === false) {
echo mysql_errno().': '.mysql_error();
}
while ($obj = mysql_fetch_object($res)) {
echo $obj->result;
}
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();
You can call a stored procedure using the following syntax:
$result = mysql_query('CALL getNodeChildren(2)');
