用法也简单，传入的参数为QQ号码，函数返回1则表示QQ在线，函数返回0则表示QQ不在线，返回小于0则表示出错。
注：需要QQ是用QQ2004II beta1或以上版本登陆才可以检测得到。
代码如下：
<?php

} else {

return( $ret );

注：以上为抛砖引玉，各位可以以此参照写出其他语言的版本；
附：不用程序，得到一个用户QQ在线状态(把下面代码另存为一个.htm文件即可)
<script language=vbscript>
Function GetURL(url)
Set Retrieval = CreateObject("Microsoft.XMLHTTP")
With Retrieval
.Open "GET", url, False, "", ""
.Send
GetURL = .ResponseText
End With
Set Retrieval = Nothing
End Function
