PHP用curl抓取https页面源代码

这里就直接上代码了：

function curl($url){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5000);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/600.1.3 (KHTML, like Gecko) Version/8.0 Mobile/12A4345d Safari/600.1.4'));
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        $contents = curl_exec($ch);
        curl_close($ch);//关闭一打开的会话
        return $contents;
    }

其中curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);这两句是关键。
