USE THE FOLLOWING PHP CODE TO ANSWER THE QUESTIONS

public function countAll_BySearch($search_term){ // select query // read products by search term $query = "SELECT COUNT(*) as total_rows FROM " . $this->table_name . " p WHERE p.name LIKE ? OR p.description LIKE ?"; // prepare query statement $stmt = $this->conn->prepare( $query ); // bind variable values $search_term = "%{$search_term}%"; $stmt->bindParam(1, $search_term); $stmt->bindParam(2, $search_term); $stmt->execute(); $row = $stmt->fetch(PDO::FETCH_ASSOC); return $row['total_rows']; }

What does the method, countAll_BySearch(), return? What is the return value's data type, and what are the return value's contents? You might want to use var_dump or print_r to observe results.
