Hi, I’ve modified the Mini Bot Class, I’ve fixed the Facebook status update and I’ve implemented the function to post on the wall of a facebook page: suppose you have a page of a brand, and you need to update it regularly with a cron job… Very, very usefull, isn’t it?
Nothing more to say. Just download the class from Mini Bot Class page and search for setFacebookStatus method and postToFacebookPage method.

This simply php function will retrieve the links of the images from Google Images searched with a keyword. The function just calls images.google.it and parse the html to find the url of the images, in this case the urls are stored in the javascript, so the parsing doesn’t use any html tag to find data. It builds an array of urls and return it.
function getGoogleImg($k) {
$url = "http://images.google.it/images?as_q=##query##&hl=it&imgtbs=z&btnG=Cerca+con+Google&as_epq=&as_oq=&as_eq=&imgtype=&imgsz=m&imgw=&imgh=&imgar=&as_filetype=&imgc=&as_sitesearch=&as_rights=&safe=images&as_st=y";
$web_page = file_get_contents( str_replace("##query##",urlencode($k), $url ));
$tieni = stristr($web_page,"dyn.setResults(");
$tieni = str_replace( "dyn.setResults(","", str_replace(stristr($tieni,");"),"",$tieni) );
$tieni = str_replace("[]","",$tieni);
$m = preg_split("/[\[\]]/",$tieni);
$x = array();
for($i=0;$i<count($m);$i++) {
$m[$i] = str_replace("/imgres?imgurl\\x3d","",$m[$i]);
$m[$i] = str_replace(stristr($m[$i],"\\x26imgrefurl"),"",$m[$i]);
$m[$i] = preg_replace("/^\"/i","",$m[$i]);
$m[$i] = preg_replace("/^,/i","",$m[$i]);
if ($m[$i]!="") array_push($x,$m[$i]);
}
return $x;
}
This function will be included in the next version of Mini Bot Class.

I’ve found this great mini bot from Alste blog, and I’ve decided to add it to the mini bot class. This bot uses curl to connect to facebook mobile (m.facebook.com) and perform the login. Then it saves the cookies received from mobile facebook and go to the facebook mobile homepage where it sets the status making a post.
I’ve tried to make the same thing with the normal facebook, but it didn’t work. I think that mobile facebook is simpler and easier to make bots working. I’ve added this bot to the Mini Bot PHP class.
NEW
Today (28/07/2010) I’ve modified the function to handle more variables from facebook forms and it seems to work again.
//
