Get Google and Alexa rank of a domain using PHP
There are already a lot of ways to find gpr/alexa rank of a domain using php. But not all of them work on 64bit servers. Here is the code that I always use for finding the google page rank and alexa rank of a website.
Get Google Page rank
function google_page_rank($url) { // URL or domain name
if (strlen(trim($url))>0) {
$_url = eregi("http://",$url)? $url:"http://".$url;
$pagerank = trim(GooglePageRank($_url));
if (empty($pagerank)) $pagerank = 0;
return (int)($pagerank);
}
return 0;
}
function GooglePageRank($url) {
$fp = fsockopen("toolbarqueries.google.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET /search?client=navclient-auto&ch=".CheckHash(HashURL($url))."&features=Rank&q=info:".$url."&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";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
$data = fgets($fp, 128);
$pos = strpos($data, "Rank_");
if($pos === false){} else{
$pagerank = substr($data, $pos + 9);
}
}
fclose($fp);
return $pagerank;
}
}
function StrToNum($Str, $Check, $Magic) {
$Int32Unit = 4294967296; // 2^32
$length = strlen($Str);
for ($i = 0; $i < $length; $i++) {
$Check *= $Magic;
if ($Check >= $Int32Unit) {
$Check = ($Check - $Int32Unit * (int) ($Check / $Int32Unit));
$Check = ($Check < -2147483648)? ($Check + $Int32Unit) : $Check;
}
$Check += ord($Str{$i});
}
return $Check;
}
function HashURL($String) {
$Check1 = StrToNum($String, 0x1505, 0x21);
$Check2 = StrToNum($String, 0, 0x1003F);
$Check1 >>= 2;
$Check1 = (($Check1 >> 4) & 0x3FFFFC0 ) | ($Check1 & 0x3F);
$Check1 = (($Check1 >> 4) & 0x3FFC00 ) | ($Check1 & 0x3FF);
$Check1 = (($Check1 >> 4) & 0x3C000 ) | ($Check1 & 0x3FFF);
$T1 = (((($Check1 & 0x3C0) < < 4) | ($Check1 & 0x3C)) << 2 ) | ($Check2 & 0xF0F );
$T2 = (((($Check1 & 0xFFFFC000) << 4) | ($Check1 & 0x3C00)) << 0xA) | ($Check2 & 0xF0F0000 );
return ($T1 | $T2);
}
function CheckHash($Hashnum) {
$CheckByte = 0;
$Flag = 0;
$HashStr = sprintf('%u', $Hashnum) ;
$length = strlen($HashStr);
for ($i = $length - 1; $i >= 0; $i --) {
$Re = $HashStr{$i};
if (1 === ($Flag % 2)) {
$Re += $Re;
$Re = (int)($Re / 10) + ($Re % 10);
}
$CheckByte += $Re;
$Flag ++;
}
$CheckByte %= 10;
if (0!== $CheckByte) {
$CheckByte = 10 - $CheckByte;
if (1 === ($Flag % 2) ) {
if (1 === ($CheckByte % 2)) {
$CheckByte += 9;
}
$CheckByte >>= 1;
}
}
return '7'.$CheckByte.$HashStr;
}
Find Alexa Rank
function alexaRank($domain){
$remote_url = 'http://data.alexa.com/data?cli=10&dat=snbamz&url='.trim($domain);
$search_for = '<POPULARITY URL';
if ($handle = @fopen($remote_url, "r")) {
while (!feof($handle)) {
$part .= fread($handle, 100);
$pos = strpos($part, $search_for);
if ($pos === false)
continue;
else
break;
}
$part .= fread($handle, 100);
fclose($handle);
}
$str = explode($search_for, $part);
$str = array_shift(explode('"/>', $str[1]));
$str = explode('TEXT="', $str);
return $str[1];
}
Hope this will help you. If you know any better(working) solution please let me know via comments.
