Description: This is a dirty page I threw together to validate an URL by actually checking the DNS rexcord fro the site supplied and then checking wether I get an 404 for the supplied path or file. The page does not look pretty, alter it to your likings.
<?php
$url = "http://dir.yahoo.com/Computers_and_Internet/Software/";
$parsed = parse_url($url);
$fullpath = "$parsed[scheme]://$parsed[host]$parsed[path]";
if ((checkdnsrr($parsed["host"],"A")) == true) {
$good_dns = true;
if (url_live($parsed["host"], $fullpath)) {
$good_url = true;
}
}
if (!$good_dns || !$good_url){
print "<p align="center"><font face="arial" size="5"><b>Page Not Found.</b></font><br><br>";
if ($good_dns && !$good_url){
print "<font face="arial" size="3"><b>Your Domain is correct but the directory/file doesn't exist.</b></font></p>";
}else{
print "<font face="arial" size="3"><b>If you feel this is in error, you may need to check your DNS.</b></font></p>";
}
die();
