Thread: Help me with this code

Hi ,

I actually coded a php to check for backlink on all the sites listed on my Proxy List Site .

I even used usleep to get over the time limit set by server people , but still the script would stop working after few checks

Here is the link you can see :

Backlink Checker

The code for same is :

PHP Code:

    <?php

    $mydomain = "http://youcanhide.com"; // Set this to your domain

   $list = file_get_contents("new.txt");
    $urls = explode ("\n", $list);

    echo "<B>Checking back links to $mydomain....</B><P><FONT SIZE=-1>";

    foreach ($urls as $url) {
echo date('h:i:s') . "<br />";

//sleep for 10 seconds
usleep(2000000);

//start again
echo date('h:i:s');

    if (strlen ($url)) {
    echo $url . "<B><FONT COLOR=";
    if (strpos (file_get_contents($url), $mydomain) != FALSE) {
    echo "GREEN> Found";
    } else {
    echo "RED> Missing";
    }
    echo "</FONT></B><BR>";
    }
    }
    echo "</FONT>";

    ?>

New.txt is written with the help of another php file which connects to DB and writes the details to new.txt

Please look into code and help me & also tell me how to add to avoid for a site which is down so it doesnt stop my script?

Yeah I had this trouble, what happened was sometimes it would hit a dead link and wouldn't resolve, and it would make the script die.
You should do this will cURL and set the timeout like 10 seconds
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,10);
curl_setopt($ch, CURLOPT_TIMEOUT,10);

instead of strpos use preg_match with a regural expression,

Code:

if(!preg_match('#<a[^>]+href\s*=\s*(["\\\']?)http://(?:www\.)?example\.com#i', $website_html)){

echo "This is bad!";

}
