我想知道如何使用 PHP 从上面的 HTML 源代码中获取此代码。就像如何从 PHP 中的 URL 回显 HTML 源中的这个特定属性一样。希望我不要要求太多。任何帮助将非常感激。提前致谢！

解决方法

要从 URL 获取源，请使用 https://www.php.net/manual/en/function.file.php，这将从特定页面获取源。

然后使用 https://www.php.net/preg_match/ 匹配您要使用正则表达式提取的确切文本。

<?php
$htmlCode = file_get_contents('YOUR WEBSITE URL HERE');
preg_match_all('/(https:\/\/video-downloads\.googleusercontent\.com\/.*\")/',$htmlCode,$output_array);
var_dump($output_array); // You can access the output here
