php代码错误，望好心人看看错在哪里！
错误提示：<br /><b>Parse error</b>: syntax error, unexpected T_IF in <b>C:\ComsenzEXP\wwwroot\php\qqrobot.php</b> on line <b>150</b><br />
【150行代码“】if($ans!='false')
【150行区域范围如下】
if ($Event == 'ReceiveNormalIM' or $Event == 'ReceiveClusterIM' or $Event== 'ReceiveTempSession' or $Event== 'ReceiveTempClusterIM')
{
//找问题答案
$ans = $DataXml->getAns($Message)
if($ans!='false')
{
echo $ans;
}
else if($Event == 'ReceiveNormalIM' or $Event== 'ReceiveTempSession')
{
echo "啊咧，这个我没有学过呢，不如你来教我吧？";
}
exit;
}
