$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.A.B.C Safari/525.13");

the url https://www.yellowpages.com.au does not serve a page, it just redirects you (via a HTTP Location Redirect ) to another url (to be specific: Location: http://www.yellowpages.com.au/dataprotection?path=/ ) that actually serves a page.网址https://www.yellowpages.com.au不提供页面，它只是将您（通过HTTP 位置重定向）重定向到另一个网址（具体来说： Location: http://www.yellowpages.com.au/dataprotection?path=/ ) 实际服务于一个页面。 in order to load that url with curl, you must tell curl to follow HTTP Location redirects , that can be done with CURLOPT_FOLLOWLOCATION ,为了使用 curl 加载该 url，您必须告诉 curl 遵循HTTP Location redirects ，这可以通过CURLOPT_FOLLOWLOCATION完成，

in addition to that, yellowpages.com.au blocks requests that lack a User-Agent header, libcurl sets no default User-Agent header, you can set that with the CURLOPT_USERAGENT option , here is a working example:除此之外，yellowpages.com.au 会阻止缺少 User-Agent 标头的请求，libcurl 没有设置默认的 User-Agent 标头，您可以使用CURLOPT_USERAGENT 选项进行设置，这是一个工作示例：

<?php
$ch=curl_init('https://www.yellowpages.com.au');
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch,CURLOPT_USERAGENT,'libcurl/'.(curl_version()['version']).' PHP/'.PHP_VERSION);
curl_exec($ch);
curl_close($ch);

outputs:输出：
