Maybe I drank too much coffee last night, but this is working for me if I
add dirname(__FILE__) to "log.txt" (PHP version 5.2.4) and not otherwise
<?php
session_start();
class a
{
public $b;
public function __sleep()
{
file_put_contents(dirname(__FILE__)."/log.txt","ok" .
PHP_EOL,FILE_APPEND);
echo "done!";
return array();
}
}
$a = new a;
$_SESSION['obj'] = $a;
?>
