How does php curl only get data?

php uses CURL to obtain data

The first one, merge POST and GET

function http_curl($url, $type = 'get', $data = ''){
  $cl = curl_init();　　//初始化
  curl_setopt($cl, CURLOPT_URL, $url);　　//设置 cURL 传输选项
  curl_setopt($cl, CURLOPT_RETURNTRANSFER, 1);　　// 将curl_exec()获取的信息以字符串返回，而不是直接输出。
　　curl_setopt($cl, CURLOPT_SSL_VERIFYPEER, false);
　　curl_setopt($cl, CURLOPT_SSL_VERIFYHOST, false);
  if($type == 'post'){
    curl_setopt($cl, CURLOPT_POST, 1);　　　　//发送 POST 请求，类型为：application/x-www-form-urlencoded
    curl_setopt($cl, CURLOPT_POSTFIELDS, $data);
  }
  $output = curl_exec($cl);　　//执行 cURL 会话
  curl_close($cl);
  return $output;
}

The second one is to separate POST and GET

POST

$url = "http://localhost/web_services.php";
　　$post_data = array ("username" => "bob","key" => "12345");  
 　　$ch = curl_init(); 
 　　curl_setopt($ch, CURLOPT_URL, $url);
　　curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
　　// post数据
　　curl_setopt($ch, CURLOPT_POST, 1);
　　curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
　　curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
　　// post的变量
　　curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); 
 　　$output = curl_exec($ch);
　　curl_close($ch); 
 　　//打印获得的数据
　　print_r($output);

GET

　　//初始化
　　$ch = curl_init();  
 　　//设置选项，包括URL
　　curl_setopt($ch, CURLOPT_URL, "http://www.jb51.net");
　　curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
　　curl_setopt($ch, CURLOPT_HEADER, 0); 
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
 　　//执行并获取HTML文档内容
　　$output = curl_exec($ch); 
 　　//释放curl句柄
　　curl_close($ch); 
 　　//打印获得的数据
　　print_r($output);

The data obtained in the above method is in json format

Use json_decode($output,true) to parse it into an array; use json_decode($output) to Parsed into an object
