# maxdb_ping

(PECL)

maxdb_ping

(no version information, might be only in CVS)

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

## Description

Procedural style:

bool maxdb_ping ( resource link )

Object oriented style (method):

class maxdb {
bool ping ( void )
}

Checks whether the connection to the server is working. If it has gone down, and global option `maxdb.reconnect` is enabled 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.

## Return values

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.

## Example

Beispiel 1. Object oriented style

`<?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } /* check if server is alive */ if ($maxdb->ping()) { printf ("Our connection is ok!\n"); } else { printf ("Error: %s\n", $maxdb->error); } /* close connection */ $maxdb->close(); ?>`

Beispiel 2. Procedural style

`<?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } /* check if server is alive */ if (maxdb_ping($link)) { printf ("Our connection is ok!\n"); } else { printf ("Error: %s\n", maxdb_error($link)); } /* close connection */ maxdb_close($link); ?>`

The above examples would produce the following output:

    Our connection is ok!
