Check if a URL Exists

[Chan]

I can't find a working function which will allow me to check if a url exists?


Can anyone provide me with one? Or help me create one?

You could always just use simple code like:

$content = fopen($url);
if ($content) {}
else {
  // URL Does not exist
} 

Or you could make a connection to port 80 and see if the connection rejects or not.
