如何检查是否有更多的网站在谷歌索引

Question

我发现一个脚本检查索引在谷歌如果网站有索引

function getPagesIndexedGoogle($site)
{
    if ($site) {
        $curl = curl_init();
        curl_setopt_array($curl, array(
            CURLOPT_HEADER => 0,
            CURLOPT_RETURNTRANSFER => 1,
            CURLOPT_URL => "https://www.google.com.au/search?q=site:$site&gws_rd=ssl",
            CURLOPT_SSL_VERIFYPEER=> false,
            CURLOPT_USERAGENT => 'Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko'
        ));
        $result_string = curl_exec($curl);
        curl_close($curl);
        if (strpos($result_string, "did not match any documents") !== false) {
            return 0;
        } else {
            $match = preg_match("/about ([0-9,]{0,12})/i", $result_string, $matches);
            echo $matches[1];
        }
    }
}
if($_POST['domain']){
    $site = $_POST['domain'];
}
echo  $_POST['domain'] ;
echo getPagesIndexedGoogle($site);    
?>

如何检查多个url?

我已经使用Foreach，但它不工作。

按照要求，这应该能成功:

<?php
function getPagesIndexedGoogle($site)
{
    if ($site) {
        $curl = curl_init();
        curl_setopt_array($curl, array(
            CURLOPT_HEADER => 0,
            CURLOPT_RETURNTRANSFER => 1,
            CURLOPT_URL => "https://www.google.com.au/search?q=site:$site&amp;gws_rd=ssl",
            CURLOPT_SSL_VERIFYPEER=> false,
            CURLOPT_USERAGENT => 'Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko'
        ));
        $result_string = curl_exec($curl);
        curl_close($curl);
        if (strpos($result_string, "did not match any documents") !== false) {
            return 0;
        } else {
            $match = preg_match("/about ([0-9,]{0,12})/i", $result_string, $matches);
            echo $matches[1];
        }
    }
}
if(!empty($_POST['domain'])){
    // Tries to split URLs by new line or space character
    $sites = preg_split('#\r\n|\r|\n| #i', $_POST['domain']);
    foreach($sites as $site){
        // Checks if the URL is a valid website or not (http(s):// must be included!)
        if(preg_match('#((https?|ftp)://(S*?.S*?))([s)[]{},;"':<]|.s|$)#i', $site)){
            echo $site;
            echo getPagesIndexedGoogle($site);
        } else {
            echo $site;
            echo " is not a valid url.";
        }
    }
} else {
    echo "No websites were entered.";
}
?>

我仍然建议你不要使用文本区，而是使用简单的文本字段。它只是不容易出错。
