于是实现了一个http请求的封装类，以方便调用。本http请求类，封装了三种post提交方法和一个request请求方法。
1，http请求封闭类

调用示例：
socket); $rs[] = $httphelper->post($url, $data); $data = array(name=>curl); $rs[] = $httphelper->post($url, $data, curl); $data = array(name=>stream); $rs[] = $httphelper->post($url, $data, stream); $rs[] = $httphelper->request($url); print_r($rs);?>
3，post.php文件：
4，输出结果：
array ( [0] => test request:array ( [name] => socket )
[1] => test request:array ( [name] => curl )
[2] => test request:array ( [name] => stream )
[3] => test request:array ( )
)
