# Using Directional Parameters
[!INCLUDE[Driver_PHP_Download](../../includes/driver_php_download.md)]

When using the PDO_SQLSRV driver, you can use [PDOStatement::bindParam](../../connect/php/pdostatement-bindparam.md) to specify input and output parameters.  
  
The topics in this section describe how to use directional parameters when calling stored procedures using the SQLSRV driver.
