PHP Curl无法加载页面

I am trying to open a specific page (https://www.yellowpages.com.au) I have tried simplehtmldom I have also tried Curl I have tried with different headers and added a certificate I can open other pages, just not this one and would like to know how the site is stopping my access and what I can do about it.

$ch = curl_init();
curl_setopt($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");


$certificate = "cacert-2019-01-23.pem";
curl_setopt($ch, CURLOPT_CAINFO, $certificate);
curl_setopt($ch, CURLOPT_CAPATH, $certificate);


$data = curl_exec($ch);
curl_close($ch);
echo $data;

Thanks

    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. in order to load that url with curl, you must tell curl to follow HTTP Location redirects, that can be done with CURLOPT_FOLLOWLOCATION,

    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:

    <?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:

    $ php foo4.php
