我正在尝试从 html 页面获取确切的域 url

我尝试这个 url 只从 v.html 返回

但我的 php 函数显示所有网址

v.html 有html代码和链接

这是我的 php 代码

<?php


$string=file_get_contents("v.html");

function getUrls($string)
{
    $regex = '/https?\:\/\/[^\" ]+/i';
    preg_match_all($regex, $string, $matches);
    return ($matches[0]);
}

 $urls = getUrls($string);

 foreach($urls as $url)
 {
    echo $url.'<br />';
 }


?>

输出

strpos()在其输出中使用 PHP 函数。与他一起搜索“https”并找到您的网址

$findme   = 'https://';
$pos = strpos($output, $findme);

// Note our use of ===.  Simply == would not work as expected
if ($pos === false) {
    // not found in the output
} else {
    // found in the output
}

或试试这个：

foreach($urls as $url) { 
   if (strstr($url,'picasaweb.google.com')) { 
      echo $url; 
   } 
}

使用 JavaScript，您可以使用

this.document.location.href
