Create configuration files and write your own BLOG system using PHP 2_PHP tutorial

Let’s take a look at the renderings first

Pre-creation file interface

After creating the configuration file, the interface will prompt that repeated installation is not possible

Let’s enter the code below. The code for the html interface will not be uploaded. Just enter the PHP code directly

Copy the code The code is as follows:

/*
FILE:install.php
Author:www.5dkx.com
DATE:2010-3-29
DONE: Install configuration file
*/
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($fp,"<"."?phprn ");
fwrite($fp,"$host="$host";rn");
fwrite($fp,"$user="$user";rn");
fwrite( $fp,"$passwd="$passwd";rn");
fwrite($fp,"$dbname="$dbname";rn");
fwrite($fp,"$sitename=" $sitename";rn");
fwrite($fp,"$siteurl="$siteurl";rn");
fwrite($fp,"$sitekeyword="$sitekeyword";rn");
fwrite($fp,"$sitedescription="$sitedescription";rn");
$tmp = "$conn = mysql_connect($host,$user,$passwd)or die(mysql_error()); rn";
fwrite($fp,$tmp);
$tmp ="mysql_query("set names 'gbk'")or die("Failed to set character library!");rn";
fwrite($fp,$tmp);
$tmp ="mysql_select_db($dbname,$conn)or die("Failed to connect to database!");rn";
fwrite($fp,$tmp);
fwrite($fp,"?>rn");
flock($fp,LOCK_UN);
echo "File configuration successful!
";
echo "";


}
else
{
echo "can 't lock the file!
";
}
fclose($fp);
$fins = fopen("install_lock.txt","w");
fclose($ fins);
}
else
{
echo "install_locak.txt already exists, please delete this file if you want to reinstall!

It will prompt that repeated installation is not allowed. Next, enter the code. Well, I won’t upload the code for the html interface. Just upload the PHP code and copy it...
