You need to get every player on the account by using regex or some string manipulation... then load each tibia char and extract is level from the html.
PHP Code:
$somestring = curl_download("http://www.tibia.com/community/?subtopic=characters&name=meh")
print "this chars level is " + get_string_between($somestring ,"<td>Level:</td><td>","</td></tr>" )
function get_string_between($string, $start, $end){
$string = " ".$string;
$ini = strpos($string,$start);
if ($ini == 0) return "";
$ini += strlen($start);
$len = strpos($string,$end,$ini) - $ini;
return substr($string,$ini,$len);
}
function curl_download($Url){
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $Url);
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
