Guide for Building Web Application Using PHP and Mysql
1. Download and install PHP, Web Server, and MySql from one of the following sites. You
can look up the lecture notes on the class webpage for tutorials of HTML, PHP and more to
create webpages as needed.
1. http://www.microsoft.com/web/webmatrix/
2. http://sourceforge.net/projects/wampserver/
PHP is compatible with various web servers like Apache and the Microsoft’s IIS as well. All the
PHP scripts are executed on the server (Apache, IIS etc) and it supports various databases like
MySQL, Oracle, Solid, Generic ODBC etc; however, it is mostly used with MySQL. A PHP file
has an extension of .phtml, .php or .php3 and it may contain various HTML tags, texts and scripts.
Although a .php file contains scripts but when it is returned to the browser, it is returned as a plain
HTML file. You can view a PHP file in Notepad as a source as well (right click on php file to
select Edit with NotePad).
Note: Some MySql Commands in an old version are deprecated in the latest versions of WAMPServer,
they will raise errors. mysqi are the new format for commands.
Note that there may be version mismatch problems. Not all versions of PHP's will run with Apache2.4.
For more info for this problem:

Additional Guide to Set up:
Edit Wamp Server icon ->PHP ->php.ini
Look at phpinfo( ) for get your server information

Sample PHP Codes with Search an employee in Company database in MySql
2. Build Search function in Company Website in root page to search an employee who is
working for the company as follow:
2-1. Company Webpage in root page “idex.html” has Search in menu. (You can list more
menu choice if you want)
2-2. Search page has Enter bar to take Last Name and two Buttons “Search” and “Reset”
2-3. On submit Search, it will connect to your database, search Employee table to find an
employee with the Last Name. Then on next page, it will display the employee information
as output: First, Last Name, Sex, Dno of the employee in Table form.
<?php
$con = mysqli_connect("localhost", "root", "") or die("Error connecting to database: ".mysqli_error());
mysqli_select_db($con, "company") or die(mysqli_error());
?>
