php之curl实现http与https请求的方法

常规curl请求：

$url = '//www.dvy.com.cn';

​$curl = curl_init();

​curl_setopt($curl, CURLOPT_URL,$url);

​curl_setopt($curl, CURLOPT_HEADER,1);

​curl_setopt($curl, CURLOPT_RETURNTRANSFER,1);

​$data = curl_exec($curl);

​curl_close($curl);

​var_dump($data);

使用curl请求HTTPS：​

$url = '//www.dvy.com.cn';

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_HEADER, 1);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);//这个是重点。

$data = curl_exec($curl);

curl_close($curl);

var_dump($data);
