Question?
 What do we need for a dynamic website?
 Dynamic: Content of pages can change depending on
factors such as time, user and etc.

XAMPP
 X ( L = Linux, M = Mac, W= Windows but X = cross-platform)
 Apache Server
 MySQL
 PHP
 Perl

Apache Server
 HTTP Server
 Written in C
 Open Source
 Windows, Linux, Mac OS X, Solaris, etc.
 By 2013 54.2% of all websites used Apache

What is HTTP?
 Hypertext Transfer Protocol
 HTTP is the foundation of data communication for
the World Wide Web.
 Hypertext is structured text that uses logical links
(hyperlinks) between nodes containing text.
 HTTP is a request-response protocol between server
and client to transfer data

Example
Request 1
Response 1
Request 2
Response 2
Request 3
Response 3

MySQL
 Relational Database Management System
 Open Source
 Written in C and C++

PHP
 PHP: Hypertext Preprocessor (recursive acronym )
 PHP is a server-side scripting language designed
for web development
 PHP code is interpreted by a web server with a PHP
processor module

Perl
 Perl is a programming language. In the web
development environment, Perl is a very powerful
way to create dynamic web pages.

PHP vs Perl?
 PHP is easier to learn
 PHP is inline scripting language while Perl is not
 It is written within HTML code
 PHP is usually faster
 Perl much more powerfull in regex (PHP actually
uses Perl to provide regex)
 Etc.

Playing Around With Configs
 How to have two different apache servers?
 What is the problem here? Why do you think that
we had to stop the previous apache server? What
if I want them to work simultaneously?

Problem?
 Both servers what to listen to the same port?
 Port 80
 We have to change setting to use different port on
XAMPP

Change Apache Port on Mac
 In Manage Servers tab, choose to highlight Apache
Web Server and click on Configure.

 Change 80 to any port above 1024. Since anything
below it is a reserved port. For example 8080 and
restart server.

 Now
 http://localhost/xampp doesn’t work anymore but
 http://localhost:8080/xampp is now active

Fix on Windows
 On windows you’ll clock on Config in the top right
corner.
 Then you’ll click on Service and Port Settings in the
new window an you’ll change 80 to 8080 in the
new window and you’ll need to also save

Change Apache Port on Windows
 Now
 http://localhost/xampp doesn’t work anymore but
 http://localhost:8080/xampp is now active

In case the GUI didn’t work
 Go to:
 Mac OS X:
 “/Applications/XAMPP/xampfiles/etc/”
 Windows:
 <USB drive letter>:apacheconf
 Open the file:
 httpd.conf
 Apply following changes:
 Find the line which specifies the port number
 “Listen 80”
 It should be at line 58 in Windows and 52 In Mac
 Change the port from 80 to anything you desire
 Save and exit the file
 Restart apache server
 Test it
 Localhost:<port number>

Safety Issues
 If you visit the security status page
 http://localhost/security/index.php
 You will se that there are three security errors

To fix this on Mac
 Run
 sudo /Applications/XAMPP/xamppfiles/xampp
security
 Then open MySQL config file using the menues and
find the line with:
 #password = your_password
 Remove # and change “your_password” to any password
you desire.

Fix on Windows
 Go to
 http://localhost/security/xamppsecurity.php
 Select password for both MySQL and XAMPP
pages.
