SYNOPSIS

       bool maxdb_ping (resource  $link)

DESCRIPTION

       Object oriented style
       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.

       nect 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
", maxdb_connect_error());
		 exit();
	      }

	      /* check if server is alive */
	      if ($maxdb->ping()) {
		 printf ("Our connection is ok!
");
	      } else {
		 printf ("Error: %s
", $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
", maxdb_connect_error());
		 exit();
	      }

	      /* check if server is alive */
	      if (maxdb_ping($link)) {
		 printf ("Our connection is ok!
");
	      } else {
		 printf ("Error: %s
", maxdb_error($link));
	      }

	      /* close connection */
	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Our connection is ok!
