How to poll for a page in PHP? pls hlp, tnx

Hi,

Ok, how do I poll for a page on a server using PHP?

If a user wanted a page that does not yet exist - but is being made at request - I'd like the script to "poke" the server to see if the page is ready to be displayed. If so, it would then transfer to that newly made page.

I read about "http_get", but do not seem to get it to work

Quote:

do
{
$flag = http_get("www.server.ext/page.htm");
}
while(!$flag);

Ok, there might be a simple way out, but I don't see it.

My info came from

http://be.php.net/manual/en/function.http-get.php

more specific:

Quote:

Returns the HTTP response(s) as string on success, or FALSE on failure.

Tnx for shedding some light, here

Just tried running it on my server and php stopped parsing the page when it reached that statement. I turned on error_reporting, but no errors...

So looking further up the php manual tree I found this statement:

Quote:

The following functions do not need the HTTP module to be present: header(), headers_list(), headers_sent(), setcookie() and setrawcookie().

http://be.php.net/manual/en/ref.http.php

So, looking further it appears you need to have pecl_http installed on your server to use http_get... see http://be.php.net/manual/en/http.install.php. (It wasn't avail on yum so i've not installed it to test, but i'd say that it'd be something to try...

Generally your server will have cURL support... http://be.php.net/manual/en/curl.examples-basic.php

Hi Brazilnut!

Thanks! Just the info I needed. On to the Batcave (the inner workings of the server involved) to install what I need!

Tnx again!!
