创建配置文件 用PHP写出自己的BLOG系统 2

今天做博客安装程序，首先做的是配置文件的创建。

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

<?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($fp,"<"."?php\r\n"); 
fwrite($fp,"\$host=\"$host\";\r\n"); 
fwrite($fp,"\$user=\"$user\";\r\n"); 
fwrite($fp,"\$passwd=\"$passwd\";\r\n");

fwrite($fp,"\$sitekeyword=\"$sitekeyword\";\r\n"); 
fwrite($fp,"\$sitedescription=\"$sitedescription\";\r\n"); 
$tmp = "\$conn = mysql_connect(\$host,\$user,\$passwd)or die(mysql_error());\r\n"; 
fwrite($fp,$tmp); 
$tmp ="mysql_query(\"set names 'gbk'\")or die(\"设置字符库失败!\");\r\n"; 
fwrite($fp,$tmp); 
$tmp ="mysql_select_db(\$dbname,\$conn)or die(\"连接数据库失败!\");\r\n"; 
fwrite($fp,$tmp); 
fwrite($fp,"?>\r\n"); 
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>"; 
} 
}
