Searching for a string in a URL

[asantos]

Hi. I need to search for a string (lets say "b55d57a3b1c9a125b896dbb249eb7e4b") on a specific website (lets say example.com).

This is the only solution i came with.

$url = 'http://example.com';
$search = 'b55d57a3b1c9a125b896dbb249eb7e4b';
$data = file_get_contents(urlencode($url));
if(strpos($data,$search)) {
echo 'OK!';
} else {
echo 'Not found...';
}

Is there a better and quickier way to do this?

Your solution is ok. You may want to strip tags before strpos if $search could possibly match some html tag. Like $search = "table".

Some would say sockets would do this job faster (fsockopen), but I doubt. Some time ago tested on loop with about 500 pages, and there was no significant time difference (1 or 2 seconds).
