Just read the contents of the page as you would read a file. PHP does the connection stuff for you. Then just look for the string via regex or simple string comparison.
只需像阅读文件一样阅读页面内容即可。PHP 为您完成连接工作。然后只需通过正则表达式或简单的字符串比较查找字符串。
$url = 'http://my.url.com/';
$data = file_get_contents( $url );
if ( strpos( 'maybe baby love you', $data ) === false )
{
// do something
}

If fopen URL wrappers are not enabled, you may be able to use the curl module (see http://www.php.net/curl)
如果未启用 fopen URL 包装器，您可以使用 curl 模块（请参阅http://www.php.net/curl）
Curl also gives you the ability to deal with authenticated pages, redirects, etc.
Curl 还使您能够处理经过身份验证的页面、重定向等。
