asp发送短信功能怎么改成php的，有asp例子，求教

If vercode > "" Then<br />email = "接口短信的用户账号"<br />SMS_PASSWORD = "接口短信的用户密码"<br />DescURL = "http://www.xxxx.com.cn/api/send.asp"  //接口地址<br />Set objHTTP = Server.CreateObject("MSXML2.XMLHTTP")<br />Call objHTTP.Open("POST", DescURL, FALSE)<br />PostData = "email="+email+"&Password="+SMS_PASSWORD+"&MsgContent="+((MsgContent))+"&mobileNumber="+ m +"&SendTime="+SendTime+"&SubNumber="+ SubNumber  //一些上边的变量拼接，有用户名，密码，发送手机号等<br />Response.Write postdata<br />Call objHTTP.SetRequestHeader("Content-Type","text/html; charset=uft-8")<br />Call objHTTP.open("GET",DescURL & "?" & PostData, false)<br />Call objHTTP.send()<br />end if

这是asp的写法，有点别扭。 要换成php怎么写啊？先谢谢了！
------解决思路----------------------
用curl类似的
------解决思路----------------------
file_get_contents($url);

你看这样是否能用
