checking if site/file is online? plz help

Dan39

Ok so I am making a script for like downloads from other sites, and I want to be able to show if a download is online or not, liek fi i have www.site.com/file.exe i wanna know if the site is online or even better if the file is there also

i found this script by searching, but im not sure if it works for domains...

function serverStatus() {
  if ($fp = @fsockopen("192.168.2.1", 80, $errno, $err,2)) {
      return true;
    } else {
      return false;
    }
}

and this is a custom function, which i never use custom functions, i dunno why, jus havnt dont that much coding that requires functions, how do i use functions like that, that i have made, in my scripting? would i do like, if ( serverStatus() == 1 ) light = green
else light = red

thnx =]

execute

if ( serverStatus() == TRUE ) $light = green;
else $light = red;

yep

and use "www.site.com/file.exe" inside the IP area of fsockopen

But i would be very careful to make sure no one tries to put some weird values into that... and hijack your fsock open function, which can be a dangerous hackers tool

the script will be used in a private community where we all trust each other, so im lucky i wont have to do any extra script, but if i did i would jus have to do some like preg_replace's and such right?

and for the custom function, will it work with a variable from the script? it looks like it doesnt, do i have to se thte variable in the parenthessis when i do he function?

when i set the domain in the function it says "Warning: fsockopen(): php_network_getaddresses: gethostbyname failed"

execute

well maybe you need to not type the file name.. you'll have to experiment... try other servers etc...

You can put variables.
