请教,php如何获取远程JSon内容 并post一些参数

目的: php请求远程php页面(页面是json内容),提交一些参数(例如name,pwd字段),将json返回

希望大家给个例子

------解决方案--------------------

PHP code
$data = file_get_contents($url);//目的页面内容获取$t = json_decode($data,1);//转换为PHP数组//处理...$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $urlo);//数据发送地址curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);//发送的数据数组curl_exec($ch);<br><font color="#e78608">------解决方案--------------------</font><br>
