Why Does My PHP Code Throw \"Fatal error: Call to undefined method mysqli_stmt::fetch_array()\"?

Error Resolution: undefined method mysqli_stmt::fetch_array()

The error "Fatal error: Call to undefined method mysqli_stmt::fetch_array()" indicates an incorrect method call within the provided PHP code. Specifically, the method fetch_array() is not applicable to the mysqli_stmt object.`

Explanation

When using prepared statements with MySQLi, you must use the appropriate method for fetching data. For retrieving a single row of data, use mysqli_stmt::fetch(). To retrieve multiple rows, use mysqli_result::fetch_all().

Corrected Code

<code class="php">$data = array();

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

By replacing fetch_array() with fetch(), the code will correctly fetch the records and store them in the $data array.

It's recommended to consult the MySQLi documentation (specifically mysqli_stmt::fetch() or mysqli_result::fetch_all()) for more information on data retrieval methods with prepared statements.
