Why is `mysqli_stmt::fetch_array()` causing a \"Fatal error: Call to undefined method mysqli_stmt::fetch_array()\"?

mysqli_stmt::fetch_array() Call Failure Explained

In PHP programming, the error "Fatal error: Call to undefined method mysqli_stmt::fetch_array()" occurs during database operations using MySQLi prepared statements. This arises when attempting to use the fetch_array() method on a mysqli_stmt object.

Understanding the Problem

The error indicates that fetch_array() is not a valid method for mysqli_stmt objects. Prepared statements in MySQLi have their own set of methods for fetching data, namely fetch().

Solution: Using mysqli_stmt::fetch()

To retrieve data from a prepared statement, the fetch() method should be used instead of fetch_array(). The fetch() method returns a numerically indexed array of the current row's data.

Alternative: mysqli_result::fetch_all()

If multiple rows need to be fetched, the mysqli_result::fetch_all() method can be used. This method returns an array of associative arrays representing all the rows in the result set.

Revised Code

The corrected version of your code would be:

<code class="php">...
$sql->execute();
$sql->bind_result($job);

$data = array();

while ($sql->fetch()) {
    $data[] = array(
            'label' => $job  
    );
    echo json_encode($data);
}</code>
