Migrate PHP 4 Or PHP 5 Dalam XAMPP Linux

XAMPP is an easy to install Apache distribution containing MySQL, PHP and Perl. XAMPP is really very easy to install and to use - just download, extract and start.
XAMPP Supported Platforms
a version for Linux systems (tested for Ubuntu, SuSE, RedHat, Mandrake and Debian),
a version for Windows 98, NT, 2000, 2003 and XP,
a beta version for Solaris SPARC (developed and tested under Solaris 8),
and a beta version for MacOS X.
This MacOSX and Solaris versions of XAMPP are still in the first steps of development. Use at you own risk!
XAMPP for Linux Packages
The distribution for Linux systems (tested for SuSE, RedHat, Mandrake and Debian) contains: Apache, MySQL, PHP & PEAR, Perl,ProFTPD, phpMyAdmin, OpenSSL, GD, Freetype2, libjpeg, libpng, gdbm, zlib, expat, Sablotron, libxml, Ming, Webalizer, pdf class, ncurses, mod_perl, FreeTDS, gettext, mcrypt, mhash, eAccelerator, SQLite and IMAP C-Client.
Install XAMPP in Debian
First you need to download the latest version of XAMPP from here .At the time of writing this article XAMPP version is 1.5.5a.
wget http://kent.dl.sourceforge.net/sourceforge/xampp/xampp-linux-1.5.5a.tar.gz
Now you should be having xampp-linux-1.5.5a.tar.gz file in your downloaded location
Go to a Linux shell and login as root:
$su -
Extract the downloaded archive file to /opt
#tar xvfz xampp-linux-1.5.5a.tar.gz -C /opt
XAMPP is now installed below the /opt/lampp directory.
Start XAMPP Server
To start XAMPP simply Use the following command
#/opt/lampp/lampp start
Starting XAMPP 1.5.5a…
LAMPP: Starting Apache…
LAMPP: Starting MySQL…
LAMPP started.
Test Your XAMPP Installation
OK, that was easy but how can you check that everything really works? Just type in the following URL at your favourite web browser:
XAMPP Security Configuration
XAMPP is not meant for production use but only for developers in a development environment. The way XAMPP is configured is to be open as possible and allowing the developer anything he/she wants. For development environments this is great but in a production environment it could be fatal.
Here a list of missing security in XAMPP:
The MySQL administrator (root) has no password.
The MySQL daemon is accessible via network.
ProFTPD uses the password “lampp” for user “nobody”.
PhpMyAdmin is accessible via network.
Examples are accessible via network.
MySQL and Apache running under the same user (nobody).
To fix most of the security weaknesses simply call the following command
#/opt/lampp/lampp security
It starts a small security check and makes your XAMPP installation more secure.
Switching between PHP4 and PHP5
Because such very new versions like PHP 5 always should be handled with care XAMPP team decided to include both current versions of PHP into XAMPP since version 1.4.7: PHP 5.x and PHP 4.x. If you find out your PHP application doesn’t work with PHP 5 you will be able to switch back easily to PHP 4.
By the following command you can switch “back” to PHP 4.x
#/opt/lampp/lampp php4
And with the following command you can switch back to PHP 5.x
#/opt/lampp/lampp php5
If you forgot which version of PHP is in use simply use phpinfo() or call this command
#/opt/lampp/lampp phpstatus
Start And Stop XAMPP Server Services
