(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

Возвращает `TRUE` в случае успешного завершения или `FALSE` в случае возникновения ошибки.

## Example

Пример 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();
?>`

Пример 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!
