how about building on this:
// try and open the link
$file = fopen($link,"r"); // Note if safe mode is on, fopen might not
//open URLs
// Look for a "404" code
eregi($file, "404",$errorCode) // greps the file looks for the text
// "404" and put is into an array
// check to see if the array holds data
if($errorCode) // if this is TRUE, the file does not exist
{
echo "there has been an error";
exit;
}
else
{
// Code to add to database
}
Don't know if this will work, but it's an idea... :)

Matt
