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

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，如Gecko）Chrome / 0.ABC 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. 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
