PHP根据URL获取网页源码

function get_html($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
    curl_setopt($ch, CURLOPT_HTTPHEADER,
        array(
            'pragma: no-cache',
            'cache-control: no-cache',
            'sec-ch-ua: " Not A;Brand";v="99", "Chromium";v="96", "Google Chrome";v="96"',

            'content-type: application/json',
            'sec-ch-ua-mobile: ?0',
            'user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.93 Safari/537.36',
