mysqli_stmt :: get_result（）调用undefined [duplicate]

Question

• Call to undefined method mysqli_stmt::get_result 10 answers

I am changing all my scripts to prepared statements with mysqli and I have a problem. I get this error when I use get_result() and I don't know why. My php version is 5.3.

Here is the code I use:

$user=$_GET['user'];
$stmt = $dbc->prepare("select * from `users` where id= ? and stare!=1"); 
$stmt->bind_param('s', $user);
$stmt->execute();
$result = $stmt->get_result();
if ($row = $result->fetch_assoc()) {

//do something

}

Error:

Call to undefined method mysqli_stmt::get_result() in /home/websoft/public_html/twingoo/engine/app/profil_edit.php on line 13

I encountered this problem recently.

You need to make sure that the mysqlnd extension is installed for that particular part of mysqli to work.

Depending on if you are using Windows or Linux (and what flavor of either) will determine how this is done.

In CentOS, it is pretty straight-forward :

yum install php-mysqlnd

And to confirm it is installed, you can create a php page with the following :

<?php
phpinfo();
?>

Then look for mysqlnd or native

You can also validate it is installed by

php -m | grep mysqlnd

OR

php -i | grep mysqlnd
