What's wrong with mysqli::get_result?

Question

I have the following code:

$postId = $_GET[\'postId\'];
$mysqli = new mysqli(\'localhost\', \'username\', \'database\', \'name_db\');
mysqli_report(MYSQLI_RE         


        

Answer 1

check to see it your PHP mysql native driver is enable. get->result() only works when mysql native driver is enable. http://www.php.net/manual/en/mysqli-stmt.get-result.php

Answer 2

As others have stated, it is only available in bleeding edge PHP. You could do something like this (answer to a similar question):

function bind_array($stmt, &$row) {
    $md = $stmt->result_metadata();
    $params = array();
    while($field = $md->fetch_field()) {
        $params[] = &$row[$field->name];
    }

    call_user_func_array(array($stmt, 'bind_result'), $params);
}

// ....
bind_array($stmt, $info);
$stmt->fetch();

echo json_encode($info);

Or use mysqli::query if you have a simple query with no parameters - don't use it with dynamically generated SQL-statements.

Answer 3

As mentioned in php documentation mysqli_stmt::get_result, this method is supported since PHP 5.3.0.

And it is stated in the user notes section that:

This method requires the mysqlnd driver. Othervise you will get this error: Call to undefined method mysqli_stmt::get_result()

Answer 4

The manual page doesn't give any clear information on which minimum version of PHP is needed for get_result() to work:

(No version information available, might only be in SVN)

I don't know the background to this, but it may simply not be available in your PHP version.

You could use fetch() instead.

Answer 5

I´m guessing it´s the line below that, change:

$info = $result->fecth_array(MYSQLI_ASSOC);

to:

$info = $result->fetch_array(MYSQLI_ASSOC);

Answer 6

You're probably using old version of PHP not supporting get_result() as stated on manual page
