Here is what I want to do..
Lets say I am looking for the link "example.com" in a file at http://example.com/test.html".
I want to take a PHP script that looks for an in the mentioned website. However, I also need it to work if there is a class or ID tag in the <A>.
See below url
How can I check if a URL exists via PHP?
or try it
$file = 'http://www.domain.com/somefile.jpg';
$file_headers = @get_headers($file);
if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
$exists = false;
}
else {
$exists = true;
}
From here: http://www.php.net/manual/en/function.file-exists.php#75064
...and right below the above post, there's a curl solution:
function url_exists($url) {
if (!$fp = curl_init($url)) return false;
return true;
}
Update code:-
You can use SimpleHtmlDom Class for find id or class in tag
see the below URL

Here is what I have found in case anyone else needs it also!
$url = "http://example.com/test.html";
$searchFor = "example.com"
$input = @file_get_contents($url) or die("Could not access file: $url");
$regexp = "<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>(.*)<\/a>";
if(preg_match_all("/$regexp/siU", $input, $matches, PREG_SET_ORDER)) {
foreach($matches as $match) {
echo $match[2];
if ($match[2] == $searchFor)
{
$isMatch = 1;
} else {
$isMatch= 0;
}
// $match[0] = A tag
// $match[2] = link address
// $match[3] = link text
}
}
if ($isMatch)
{
echo "<p><font color=red size=5 align=center>The page specified does contain your link. You have been credited the award amount!</font></p>";
} else {
echo "<p><font color=red size=5 align=center>The specified page does not have your referral link.</font></p>";
}
