php调用接口的应用小实例

 1 //GET方式的直接使用
 2 /*$file_contents = file_get_contents('http://localhost/Json/API.php?a=get_users&uid=10001&type=json');
 3 echo $file_contents;*/

 6 //POST方式得用下面的(需要开启PHP curl支持)。
 7 $url = 'http://localhost/Json/API.php?a=get_users&uid=10001&type=json';
 8 $ch = curl_init ();
 9 curl_setopt ( $ch, CURLOPT_URL, $url );

12 curl_setopt ( $ch, CURLOPT_POST, 1 ); //启用POST提交
13 $file_contents = curl_exec ( $ch );
