Creare form

Creare form

Salve, avrei necessità di creare un form che richiami quindi gli url inseriti per mostrare il loro pagerank, in questo momento con il codice corrente fa solo in modo che mostra il pr da un url pre-impostato, ma io vorrei un form. Questo è il primo codice:

class GooglePageRankChecker {


	// Track the instance
	private static $instance;


	// Constructor
	function getRank($page) {
		// Create the instance, if one isn't created yet
		if(!isset(self::$instance)) {
			self::$instance = new self();
		}
		// Return the result
		return self::$instance->check($page);
	}


	// Convert string to a number
	function stringToNumber($string, $check, $magic) {
		$int32 = 4294967296;  // 2^32
		$length = strlen($string);
		for ($i = 0; $i < $length; $i++) {
			$check *= $magic;
			// If the float is beyond the boundaries of integer (usually +/- 2.15e+9 = 2^31),
			// the result of converting to integer is undefined
			// refer to http://www.php.net/manual/en/language.types.integer.php
			if($check >= $int32) {
				$check = ($check - $int32 * (int) ($check / $int32));
				// if the check less than -2^31
				$check = ($check < -($int32 / 2)) ? ($check + $int32) : $check;
			}
			$check += ord($string{$i});
		}
		return $check;
	}


	// Create a url hash
	function createHash($string) {
		$check1 = $this->stringToNumber($string, 0x1505, 0x21);
		$check2 = $this->stringToNumber($string, 0, 0x1003F);


		$factor = 4;
		$halfFactor = $factor/2;


		$check1 >>= $halfFactor;
		$check1 = (($check1 >> $factor) & 0x3FFFFC0 ) | ($check1 & 0x3F);
		$check1 = (($check1 >> $factor) & 0x3FFC00 ) | ($check1 & 0x3FF);
		$check1 = (($check1 >> $factor) & 0x3C000 ) | ($check1 & 0x3FFF);


		$calc1 = (((($check1 & 0x3C0) << $factor) | ($check1 & 0x3C)) << $halfFactor ) | ($check2 & 0xF0F );
		$calc2 = (((($check1 & 0xFFFFC000) << $factor) | ($check1 & 0x3C00)) << 0xA) | ($check2 & 0xF0F0000);


		return ($calc1 | $calc2);
	}


	// Create checksum for hash
	function checkHash($hashNumber) {
		$check = 0;
		$flag = 0;


		$hashString = sprintf('%u', $hashNumber);
		$length = strlen($hashString);


		for ($i = $length - 1;  $i >= 0;  $i --) {
			$r = $hashString{$i};
			if(1 === ($flag % 2)) {
				$r += $r;
				$r = (int)($r / 10) + ($r % 10);
			}
			$check += $r;
			$flag ++;
		}


		$check %= 10;
		if(0 !== $check) {
			$check = 10 - $check;
			if(1 === ($flag % 2) ) {
				if(1 === ($check % 2)) {
					$check += 9;
				}
				$check >>= 1;
			}
		}
		return '7'.$check.$hashString;
	}


	function check($page) {


		// Open a socket to the toolbarqueries address, used by Google Toolbar
		$socket = fsockopen("toolbarqueries.google.com", 80, $errno, $errstr, 30);


		// If a connection can be established
		if($socket) {
			// Prep socket headers
			$out = "GET /tbr?client=navclient-auto&ch=".$this->checkHash($this->createHash($page)).
              "&features=Rank&q=info:".$page."&num=100&filter=0 HTTP/1.1\r\n";
			$out .= "Host: toolbarqueries.google.com\r\n";
			$out .= "User-Agent: Mozilla/4.0 (compatible; GoogleToolbar 2.0.114-big; Windows XP 5.1)\r\n";
			$out .= "Connection: Close\r\n\r\n";


			// Write settings to the socket
			fwrite($socket, $out);


			// When a response is received...
			$result = "";
			while(!feof($socket)) {
				$data = fgets($socket, 128);
				$pos = strpos($data, "Rank_");
				if($pos !== false){
					$pagerank = substr($data, $pos + 9);
					$result += $pagerank;
				}
			}
			// Close the connection
			fclose($socket);


			// Return the rank!
			return $result;
		}
	}
}

Il secondo, dove appunto rilascia il risultato:

<?php
include 'GooglePR.class.php';
$pr = new GooglePageRankChecker();
$google_pageRank = $pr->getRank("google.com");
print 'PR: ' . $google_pageRank;
?>

Grazie a chi mi vorrà aiutare,
