MYSQL查詢解決方案

MYSQL查詢
if (substr($remessage,0,2)== 'TP '){
$PSN=str_replace( 'TP ', ' ',$remessage);
echo $PSN;
exit;
sql= "select id from tempnum where id= ' ".intval($PSN). " ' ";
$rs=$conn-> execute($sql);
if ($rs-> EOF)
{
SMSSendReturnStr($config[ 'sp '],$rs-> fields[ "MobileNum "], '對不起，請沒有找到您要投票的人，請核對。謝謝您的參與 ');
}
else{
$conn-> execute( "update tempnum set PS=PS+1 where id= ' ".$PSN. " ' ")
}
break;
exit;

}

--------------------------------------
$remessage是使用者通過手機發來的簡訊 ,格式為TP000001 TP後面是數字對應的ID,但是不知道為什麼總是查詢那出錯,先簡訊格式正確
