mysql存储过程不起作用

Question

I am trying to call a mysql stored procedure using the following code:

 $mysqli = new mysqli("localhost", "user", "password", "mydatabase");
 $result = $mysqli->query('CALL storedproc_allusers()');

 while($row = $result->fetch_array(MYSQLI_BOTH))
 {
 echo $row['email'] . "<br />";
 }

The stored procedure is:

 USE `mydatabase`$$
 DROP PROCEDURE IF EXISTS `storedproc_allusers`$$
 CREATE DEFINER=`user`@`xx.xxx.xx.xx` PROCEDURE `storedproc_allusers`()
 BEGIN
 SELECT * FROM users;
 END$$
 DELIMITER ;

I know my connection to the db is good because if I run a simple select query I get what I expect.

I get the following error when I run the above:

Fatal error: Call to a member function fetch_array() on a non-object etc. etc. which leads me to think nothing is being returned from the query.

I use SQLYOG and can successfully run the procedure from there. Any help would be appreciated.

You can find multiple examples here http://php.net/manual/en/mysqli.quickstart.stored-procedures.php .

$mysqli = new mysqli("localhost", "user", "password", "mydatabase");
$mysqli->query('CALL storedproc_allusers()');
do {
    if ($result = $mysqli->store_result()) {
        var_dump($result->fetch_all());
        $result->free();
    }
} while ($mysqli->more_results() && $mysqli->next_result()) ;

Try this
