创建前文件界面   

创建配置文件后界面，会提示不能重复安装

下面就上代码吧，html界面的代码就不上了，直接上PHP代码吧
复制代码 代码如下:
<?php
/*
FILE:install.php
Author:www.5dkx.com
DATE:2010-3-29
DONE:安装配置文件
*/
if($_POST[mysubmit])
{
$host = $_POST[hostname];
$user = $_POST[user];
$passwd = $_POST[passwd];
$dbname = $_POST[dbname];
$siteurl = "http://".$_POST[siteurl];
$sitekeyword = $_POST[sitekeyword];
$sitedescription = $_POST[sitedescription];
$sitename = $_POST[sitename];
if(!file_exists("install_locak.txt"))
{
$fp = fopen("./include/config.func.php","w+");
if(flock($fp,LOCK_EX))
{
fwrite($fp,"<"."?php ");
fwrite($fp,"$host="$host"; ");
fwrite($fp,"$user="$user"; ");
fwrite($fp,"$passwd="$passwd"; ");
fwrite($fp,"$dbname="$dbname"; ");
fwrite($fp,"$sitename="$sitename"; ");
fwrite($fp,"$siteurl="$siteurl"; ");
fwrite($fp,"$sitekeyword="$sitekeyword"; ");
fwrite($fp,"$sitedescription="$sitedescription"; ");
$tmp = "$conn = mysql_connect($host,$user,$passwd)or die(mysql_error()); ";
fwrite($fp,$tmp);
$tmp ="mysql_query("set names "gbk"")or die("设置字符库失败!"); ";
fwrite($fp,$tmp);
$tmp ="mysql_select_db($dbname,$conn)or die("连接数据库失败!"); ";
fwrite($fp,$tmp);
fwrite($fp,"?> ");
flock($fp,LOCK_UN);
echo "文件配置成功!<br>";
echo "<script language="javascript">window.location.href="install2.php";</script>";


}
else
{
echo "can"t lock the file!<br>";
}
fclose($fp);
$fins = fopen("install_lock.txt","w");
fclose($fins);
}
else
{
echo "install_locak.txt已经存在，要想重新安装请删除此文件!<br>";
}
}
?>
