mysqli_close

(PHP 5, PHP 7)

mysqli::close -- mysqli_closeCloses a previously opened database connection

설명

객체 기반 형식

bool mysqli::close ( void )

절차식 형식

bool mysqli_close ( mysqli $link )

Closes a previously opened database connection.

Open non-persistent MySQL connections and result sets are automatically destroyed when a PHP script finishes its execution. So, while explicitly closing open connections and freeing result sets is optional, doing so is recommended. This will immediately return resources to PHP and MySQL, which can improve performance. For related information, see freeing resources

I've had situations where database connections appeared to persist following php execution. So, now, my __destructor function explicitly contains a $cxn->close(). It hurts nothing, and helps avoid memory leaks.
