Can you verify a url with php?

digitalgravy · 03-01-2004, 12:40 PM

I am trying to re-create an ASP script I found, but I am having trouble with it.

I am trying to verify if a file exists on a remote web server. Specifically a favicon.ico file.

In the ASP script it uses a function called HttpExists() and I can't seem to find an equivalent in php. I tried file_exists() but that does not work.

Is there a way to verify a url to see if it is a valid document?

Thanks

My PHP might be a little rusty, so it might need some tweaking... but this should work

Code:

<?php
    if ( @fopen("http://www.domain.com/favicon.ico") )
        echo "Its there!!";
    else
        echo "sorry...";
?>

Double check the fopen function as I dont use to much File IO but that should work
http://www.php.net/fopen

Thanks elitecodex,

You sent me in the right direction. At first it did'nt work, but then I reviewed the php manual for that function and added the "r" option for read only mode and it works. Thanks, Ill post a link to the final product when I'm done.

Thanks again!
