Querying the Database with PDO

To retrieve a result set from a database using PDO, use the PDO::query() method. To escape a value included in a query (e.g., from $_GET, $_POST, $_COOKIE, etc.) use the PDO::quote() method. PDO will ensure that the string is quoted properly for the database used.

Not all database drivers for PDO implement the PDO::quote() method. For this reason, and to ensure the best possible approach to security, it is best to use prepared statements and bound parameters, described in the next section.
