# maxdb_ping

# maxdb->ping

(PECL maxdb:1.0-7.6.00.38)

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):

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

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example#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();
?>`

Example#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!
