捲曲反向鏈接檢查，沒有任何反應

Question

好了，我想提出一個反向鏈接檢查，我有以下代碼：

$url = strip_tags($_POST['domain']); 
$url = str_ireplace('www.','http://', $url); 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$result = curl_exec($ch); 
curl_close($ch); 
return $result; 

$result1 = file_get_html('https://www.google.com/search?q='. urlencode($url).''); 

$getResults1 = $result1->find('div[id=resultStats]', 0)->innertext; 
$getResults1 = str_replace("About ", "", $getResults1); 
$getResults1 = str_replace(" results", "", $getResults1); 
$getResults1 = str_replace(",", "", $getResults1); 

echo "About".$getResults1; 

的問題是，我不回

echo "About".$getResults1; 

得到什麼據supossed回顯的結果

試試這個功能是我使用之前：

function getPage ($url) 
{ 
    $url = 'http://www.google.com/search?q='.urlencode($url); 
    if (function_exists('curl_init')) { 
     $ch = curl_init($url); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
     @curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
     curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); 
     curl_setopt($ch, CURLOPT_REFERER, 'http://www.google.com/search?hl=en&q=google&btnG=Google+Search'); 
     return curl_exec($ch); 
    } else { 
     return file_get_contents($url); 
    } 
} 

$html = getPage("http://stackoverflow.com/"); 

preg_match('/([0-9\,]+) results<nobr>/si', $html, $match); 
$value = $match[1] ?: 0; 

echo $value;
