Newbie question: "Time-based events" ?

[Anon]

Hello,

I am new with PHP and I have a question:
How can I program a script, which replaces every 10 Secons the content of a site?

I tried it this way:

do {

echo[...]
sleep(5)

} while(1);

MY QUESTIONS:
- The sleep Function didn't work... Is there any other "timer"-Function? I need a function which calls every 5 seconds a function in my code...
- Is there any function to CLEAR the screen (i mean, the text which i wrote with "echo...")

THANKS!!!

You can't have a php program run constantly, otherwise nothing would be sent to the browser.

What you probably want to do is use an HTML header that refreshes the page after 10 seconds. Then you're PHP code would update whatever was echo'd with some new information...

Hope that helps...

Here is an example of an html tag John Holmes told you about:

add this tag to your output in php (just under the head tag):

<meta http-equiv="refresh" content="10;URL=self.php">

In this: 10 is the number of seconds before refreshing and self.php is the url it should refresh to.

lets say you were displaying a random quote, then everything your page refreshes, it SHOULD display a different quote each time

hope this helps and good luck :-)

Now if you were trying to make this independent of the
actual php filename, you would say:

...URL=$PHP_SELF
