clean php output cache

[mshen]

I am working with a flash application with php. I need use clean php output cache function. so flash can reload the php code when flash refresh ,so the flash can display new data ,not from cache.

I work with ASP before.I use

 Response.Expires=-1     in ASP

Do you know php function can do the same job.

Thanks

ASP document description is here:

Response.Expires

The Expires property specifies the length of time before a page cached on a browser expires. If the user returns to the same page before it expires, the cached version is displayed.

Syntax
Response.Expires [= number]

I need the same function in PHP

Thanks

There is no function.

You just need to send the appropriate HTTP Header.
www.php.net/header
