[PHP] Re: Executing Script through image
It is a couple of seconds slow. Treating the file as an image means that the rest of the page can still load while it is doing the reverse DNS lookup and executing the script. Anyway I have got the answer now -- JJ Harrison [EMAIL PROTECTED] www.tececo.com Richard Lynch [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]... When the nessicary include file is included it does a reverse-DNS lookup to find the remote host's DNS name. The problem with this is that is seems slow(at least on my test server with a DSL connection). How slow? There's, like, a couple seconds slow, which is just how slow reverse-DNS can be, and *MINUTES* slow... Minutes slow, most likely, indicates that where-ever you are trying to look up the DNS records is trying to do a reverse DNS on *YOU* (or, rather, PHP's web-server) and timing out. If you have any control over that machine where you are doing the reverse-DNS, be sure they have your IP address associated with a name. For DSL, you can use something like http://dyndns.org to give your dynamic IP address a domain name. There are dozens of competitors to http://dyndns.org, and feel free to shop around.

The problem is that I don't know how to output the image with PHP. Like, I don't even understand the theory here... How would the script being in a file (and where is it now?) make the DNS lookups any faster? I'm so confused.

I am making a stats program.
When the nessicary include file is included it does a reverse-DNS lookup
to
find the remote host's DNS name. The problem with this is that is seems
slow(at least on my test server with a DSL connection). I thought the best
way to speed things up would be putting the entire script into a file and
then using img src=stats.php within the page. The problem is that I
don't know how to output the image with PHP.
The image would not be dynamic just a file on the server.
I would appreciate peoples comments or other suggestions

Re: [PHP] Re: Executing Script through image
instead of
$fn=fopen($filename,rb);
while(!feof($fn)) {
echo fread($fn, 4096);
}
use
readfile($filename);
