It’s showtime! Feel free to change the value of the

$url

variable in

check_links.php

if you

want to check another URL, then load

http://seophp.example.com/check_links.php

.

The output should look like the one in Figure 13-3.

Figure 13-3

Figure 13-3 shows various data that the link library could provide about the input URL,

http://

www.cristiandarie.ro/pages/seophp.aspx

. As you can see, this URL does a 301 redirect to

http://www.cristiandarie.ro/seo-php/

.

Basically, all you’re usually interested in is the final status code reached by this page. If it’s 200, then the

link is valid. This is the code that retrieves the last status code:

// stablish the URL to analyze

$url = “

http://www.cristiandarie.ro/pages/seophp.aspx

“;

// obtain redirection path

$path = LinkChecker::getPath($url, $responseCode);

// display the HTTP status code of the last request

echo ‘Final status code: ‘ . $responseCode . ‘<br />’;
