Google cache for your search site

[P_R]

I purchased a search script recently and for the cache it just had a hyperlink to googles cache, I didnt want this, I wanted it on my own site, as if it was my own cache, I couldnt find anything already made so I created this small php script.

To use the cache simply encode the URL you want the cache of

eg if you have $searchkw and $url in your current search script, and you want to create a hyperlink to the cache, you would simply do:

<?php
$enc_url = base64_encode($url);
echo"<a href=\"cache.php?u=$url&q=$searchkw\">Cached Version</a>\n";
?>

If you dont want keyword highlighting on, simply remove the &q=$searchkw

My example:
http://plerocs.com/result/20/chuck+norris

Click on cached page to see the script in action.

<?php
$url = $_GET['u'];
$url = base64_decode($url);
$kw = $_GET['q'];
$kw = str_replace(" ", "+", "$kw");
$useragent = $_SERVER['HTTP_USER_AGENT'];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://209.85.173.132/search?q=cache:$url+$kw");
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_REFERER,"http://google.com");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$contents = curl_exec ($ch);
curl_close ($ch);

$contents = str_replace("This is Google's cache of", "This is our cache of", "$contents");
$contents = str_replace(" <a href=\"http://www.google.com/intl/en/help/features_list.html#cached\" style=\"text-decoration:underline;color:#00c\">Learn more</a>", "", "$contents");
$contents = str_replace("<a href=\"http://209.85.173.132/search?q=cache:$url+$kw&hl=en&strip=1\" style=\"text-decoration:underline;color:#00c\">Text-only version</a>", "", "$contents");
$contents = str_replace("These search terms are highlighted", "Your search terms are highlighted", "$contents");

if(strpos($contents, "</b> - did not match any documents.  <br>"))
{
echo"<h1>Error</h1>\n";
echo"<hr>\n";
echo"Unfortunately the page you wanted does not yet exist in our cache. You may visit the page by clicking the link below:<br>\n";
echo"<a href=\"$url\" rel=\"nofollow\">$url</a>\n";
}else{ 
echo"$contents";
}
?>

Use it on as many of your own sites, friends sites etc as you want, if you want to release it in a script please PM me.

Is it legal to use google's cache and claim that it's your own? (see first str_replace)

Im not sure about the legality, if you have any worries I suggest you dont use the script. I myself am happy using the script, Im only doing what google does to every other webmaster. Anyway I created the script because its what I needed, I couldnt find another one out there, Use at your own risk.

Im only doing what google does to every other webmaster.

I'm just saying that Google indexes the sites and hosts it on their own servers (the caches), so the "Google's cache" is really Google's cache, whereas the "our cache" is just Google's cache with their name changed to "our".

I personally don't care, and I highly doubt Google will do anything about it, but I'm just curious.
