在PHP中window.setTimeout等效？ [英] window.setTimeout equivalent in PHP?
问题描述
有没有一种简单的方法来实现PHP等价于
window.setTimeout？
在一个javascript网络应用程序中，它通常是事情是在事件驱动的基础上完成的。例如，html元素可能有东西
就像onclick =" buttonClicked（）"表示单击该元素时应运行函数
buttonClicked。
模拟可以使用com_event_sink在PHP（在Windows上）完成。在
中，您可以通过PHP函数响应COM对象（例如，Excel，Internet Explorer，Word等）的事件。
当然，在你的PHP脚本结束时你将有一个循环到
的效果（$ GLOBALS [''keepLooping'' ]）{com_message_pump（200）; }
以便PHP脚本保留在内存中并且不会终止。那就是
，这样就可以获得那些事件回调函数。
到目前为止，非常好。
然而，让PHP函数在定时的基础上运行（没有任何
延迟循环）似乎并不那么容易，这导致我的问题：是
有一个直截了当实现PHP等效的方式
window.setTimeout？
换句话说，我希望能够在启动PHP函数之后启动它a
已经过了一定的时间。一种可能的方式来考虑这个
是一个事件驱动的睡眠。这样做的一种方法是确保我有IE的b $ ba副本，然后我可以使用IE的窗口'自己的.setTimeout来
领带它变成了PHP，但这有点凌乱，更何况我没有像IE要求那样
。

不，PHP不是一种事件驱动的语言。并且，作为一个网络应用程序，它收到
没有来自客户端的事件。
你究竟想做什么？

Is there a straightforward way of implementing a PHP equivalent to
window.setTimeout?
In a javascript web app, it''s often the case that things are done on
an event driven basis. For example, html elements might have things
like onclick="buttonClicked()" to indicate that the function
buttonClicked should be run when that element is clicked.
The analogue can be done in PHP (on Windows) using com_event_sink. In
other words, you can respond to events that a COM object (such as
Excel, Internet Explorer, Words, etc) experiences via a PHP function.
Of course, at the end of your PHP script you would have a loop to the
effect of
while ($GLOBALS[''keepLooping'']) { com_message_pump(200); }
so that the PHP script stays in memory and doesn''t terminate. That is
to say, in this way those event callback functions will be available.
So far, so good.
However, getting a PHP function to run on a timed basis (without any
delay loops) does not seem so easy, which leads to my question: Is
there a straightforward way of implementing a PHP equivalent to
window.setTimeout?
In other words, I''d like to be able to kick off a PHP function after a
certain amount of time has elapsed. One possible way to think of this
is an event driven Sleep. One way to do this is to ensure that I have
a copy of IE up, and then I can use IE''s window''s own .setTimeout to
tie it into PHP, but this is a bit messy not to mention that I don''t
like the IE requirement.
Thanks for any ideas,

No, PHP is not an event-driven language. And, as a web app, it receives
no events from the client.
What exactly are you trying to do?
