# mysqli_ping

(PHP 5 CVS only)

mysqli_ping

(no version information, might be only in CVS)

mysqli->ping -- Pings a server connection, or tries to reconnect if the connection has gone down.

## Description

Procedural style:

int mysqli_ping ( object link)

Object oriented style (method):

class mysqli {
int ping ( void )
}

Checks whether the connection to the server is working. If it has gone down, an automatic reconnection is attempted.

This function can be used by clients that remain idle for a long while, to check whether the server has closed the connection and reconnect if necessary.

mysqli_ping() returns 0 if the connection is alive and non-zero value if an error has occured.
