What debugging techniques can be used to troubleshoot issues with mysqli_stmt_get_result() not returning results in PHP?

If mysqli_stmt_get_result() is not returning results in PHP, it could be due to compatibility issues with the MySQL native driver or incorrect usage of the function. To troubleshoot this issue, you can try switching to the mysqlnd driver or double-checking your query and binding parameters. 

// Switch to the mysqlnd driver
if (!function_exists('mysqli_stmt_get_result')) {
    function mysqli_stmt_get_result($stmt) {
        $stmt->store_result();
        $result = new stdClass();
        $result->num_rows = $stmt->num_rows;
        $result->field_count = $stmt->field_count;
        $metadata = $stmt->result_metadata();
        $result->metadata = $metadata->fetch_fields();
        
        $stmt->store_result();
        $result->rows = [];
        while ($stmt->fetch()) {
            $row = [];
            foreach ($result->metadata as $field) {
                $row[$field->name] = null;
                $row[$field->name] = &$row[$field->name];
            }
            $result->rows[] = $row;
        }
        
        return $result;
    }
}
