PHP不可以写入数据库
<?php $wyname=$_REQUEST["wyname"];
$pwd=$_REQUEST["pwd"];
$sex=$_REQUEST["sex"];
$realname=$_REQUEST["realname"];
$company_name=$_REQUEST["company_name"];
$company_address=$_REQUEST["company_address"];
$postion=$_REQUEST["postion"];
$company_field=$_REQUEST["company_field"];
$mobile=$_REQUEST["mobile"];
$company_tel=$_REQUEST["company_tel"];
$fax=$_REQUEST["fax"];
$email=$_REQUEST["email"];
$website=$_REQUEST["website"];
$instant_num=$_REQUEST["instant_num"];
$sql1="insert into `wy_information` set `wyname`='$wyname',`pwd`='$pwd',`sex`='$sex',`realname`='$realname',`company_name`='$company_name',`company_address`='$company_address',`postion`='$postion',`company_field`='$company_field',`mobile`='$mobile',`company_tel`='$company_tel',`fax`='$fax',`email`='$email',`website`='$website',`instant_num`='$instant_num'";
echo $sql1;
mysql_query($sql1,$conn);
mysql_close();
不能写入MYSQL这是什么原因呀，输出的SQL语句可以在MYSQL运行。
