// VERY BEGIN OF SCRIPT
$_SERVER['HX_startTime'] = microtime(true);

...

// MY SHUTDOWN FUNCTION
register_shutdown_function('HX_shutdownFn');
function HX_shutdownFn()
{
    // formatTimeSpan is simple time to string conversion function
    var_dump(formatTimeSpan(microtime(true) - $_SERVER['HX_startTime']));
}


...

// VERY END OF SCRIPT
var_dump(formatTimeSpan(microtime(true) - $_SERVER['HX_startTime']));

我有0.0005s.在脚本结束和1.1s.在关机功能.这是正常的吗？丢失1秒？

脚本是纯php,不使用数据库连接等.在WAMP服务器上测试(php v 5.3.9,apache 2.2.21)
