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?

我有我在MySQL中创建的存储过程，并希望PHP调用该存储过程。做这个的最好方式是什么？

-MySQL client version: 4.1.11

-MySQL客户端版本：4.1.11 -MySQL Server版本：5.0.45

Here is my stored procedure:

这是我的存储过程：

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.

我现在通过使用mysqli而不是mysql找到了解决方案。

<?php 

  //connect to database
  $connection = mysqli_connect("hostname", "user", "password", "db", "port");

  //run the store proc
  $result = mysqli_query($connection, 
     "CALL StoreProcName") or die("Query fail: " . mysqli_error());

  //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.

我发现许多人似乎在使用mysql_connect，mysql_query和mysql_fetch_array时遇到问题。

You can call a stored procedure using the following syntax:

您可以使用以下语法调用存储过程：

$result = mysql_query('CALL getNodeChildren(2)');

#3

<?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;
    }

Please refer to Call a stored procedure from PHP from the Artful MySQL Tips List for calling a stored procedure

请参阅从Artful MySQL提示列表中调用PHP中的存储过程来调用存储过程

i got solution from php.net

我从php.net获得解决方案

<?php
$mysqli = new mysqli("localhost", "root", "", "joomla2.5");
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}

/*if (!$mysqli->query("DROP TABLE IF EXISTS test") ||
    !$mysqli->query("CREATE TABLE test(id INT)") ||
    !$mysqli->query("INSERT INTO test(id) VALUES (1), (2), (3)")) {
    echo "Table creation failed: (" . $mysqli->errno . ") " . $mysqli->error;
}

if (!$mysqli->query("DROP PROCEDURE IF EXISTS p") ||
    !$mysqli->query('CREATE PROCEDURE p() READS SQL DATA BEGIN SELECT id FROM test; SELECT id + 1 FROM test; END;')) {
    echo "Stored procedure creation failed: (" . $mysqli->errno . ") " . $mysqli->error;
}

if (!$mysqli->multi_query("CALL p()")) {
    echo "CALL failed: (" . $mysqli->errno . ") " . $mysqli->error;
}

do {
    if ($res = $mysqli->store_result()) {
        printf("---\n");
        var_dump($res->fetch_all());
        $res->free();
    } else {
        if ($mysqli->errno) {
            echo "Store failed: (" . $mysqli->errno . ") " . $mysqli->error;
        }
    }
} while ($mysqli->more_results() && $mysqli->next_result());
