(PHP 5, PHP 7)
mysqli::close -- mysqli_close — Closes a previously opened database connection
Object oriented style
public mysqli::close ( ) : bool
Procedural style
mysqli_close ( mysqli $link ) : bool
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
link
Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()
Returns true
on success or false
on failure.
See mysqli_connect().
Note:
mysqli_close() will not close persistent connections. For additional details, see the manual page on persistent connections.
