### Descrição

Estilo de procedimentos

bool maxdb_ping ( resource `$link` )

Estilo orientado a objetos

bool maxdb::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.

### Valor Retornado

### Exemplos

Exemplo #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();
?>`

Exemplo #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);
?>`

O exemplo acima irá imprimir algo similar a:

    Our connection is ok!
