Store the Log class definition in a file called Log.inc. The HTML page in Example uses the Log
class and PHP sessions to create a persistent log variable, $l.
Example: front.php
<?php include_once(‘Log.inc’);
session_start( );
?>
<html>
<head>
<title>Front Page</title>
</head>
<body>
<?php $now = strftime(“%c”);
if (!session_is_registered(‘l’))
{ $l = new Log(“/tmp/persistent_log”);
session_register(‘l’);
$l->write(“Created $now”);
echo(“Created session and persistent log object.<p>”);
} $l->write(“Viewed first page $now”);
echo “The log contains:<p>”;
echo nl2br($l->read( )); ?>
<a href=”next.php”>Move to the next page</a>
</body>
</html>

page triggers the loading of the persistent object $l. The _ _wakeup ( ) call reopens the logfile
