1. Installation of IIS/WAMP/XAMPP/LAMP web server and configure apache modules and php extensions. Introduction:- XAMPP is a free and open source cross-platform web server solution stack package developed by Apache Foundation, Consisting mainly of the Apache HTTP Server, MySQL database and interpreters for scripts written in the PHP. It is a simple, lightweight Apache distribution that makes it extremely easy for developers to create a local web server for testing and deployment purposes. Services needed to set up a web server – Server application (Apache), Database (MySQL Database), and Scripting language (PHP). XAMPP is also cross-platform, which means it works equally well on Linux, Mac & Windows. Windows web server deployments use the same components as XAMPP, it makes transitioning from a local test server to a live server extremely easy as well. Xampp Server uses Open SSL [Secure Sockets Layer] support. Xampp Server execution requires both Apache & MySQl Modules to be Started. Web Services run with Default URL(Uniform Resource Locator) address with https://127.0.0.1 (or) https://localhost. Xampp Services essentially require to configure with server details such as Server- name, User-name, Password, Database. System Requirements : Software Installations requires XAMPP Sever Software ( Open Source ) & Latest version of Web Browser (Google Chrome/Mozilla Firefox/ Internet Explore /Safari, etc.). In Addition to this hardware support is required with free space of 1 Giga Byte is essential with sufficient dedicated RAM (Min 1GB) for fast processing or execution. In Windows Environment :- Steps for setting up Xampp Server and Execution.
Step 1 :- Run Xampp Server Software (Open Source Software ) from local drive. Step 2 :- Click on Next to Continue installation Process.
Step 5 :- Installation Process continues. Step 6 :- Click on Finish to complete Setup.
Step 7 :- After Installation , Open Local Disk [ Where Xampp is Installed ] & find Xampp Folder [While extraction of server files, where installation is carried out ]. Step 8 :- Open Xampp Folder & Click on Xampp Control icon.
Step 11 :- Click on Start to Run MySQL Server Engine/Module. Step 12 :- Open htdocs folder.
Step 13 :- Create a New Folder with desired name or Roll number [ Ex :- Rollnumber ] Here we save all PHP programs, To execute or Run on Server. Step 14 :- Open a Text Document & write sample PHP program and save file with desired filename with Extension of .php [Example :- addition.php ] & Choose All Files while Saving at Save as Type.
Step 17 :- Choose Tool phpMyAdmin to visit MySQL Database Step 18 :- MySQL Database
Step 19 :- To execute programs, Open Web Browser and type url as localhost/folder name [ Ex:- localhost/jeevan ]. where all the programs saved in directory will display, Click on filename.php to execute. [ Ex:- addition.php ]. Step 20 :- Sample output for addition.php program.
PHP - The if…else Statement. if...else statement - executes some code if a condition is true and another code if that condition is false Syntax if ( condition ) { code to be executed if condition is true; } else { code to be executed if condition is false; } Source Code :-
**Output:-** For Value 75, You have Passed [ Default ] For Value 35, You have Failed For Value 85, You have Passed **Result:-** Hence the program executed successfully.
PHP - The if…elseis…else Statement. if...elseif....else statement - executes different codes for more than two conditions Syntax if ( condition ) { code to be executed if this condition is true; } elseif ( condition ) { code to be executed if this condition is true; } else { code to be executed if all conditions are false; } Source Code :-
**Output:-** For Value 35, Sorry! you have Failed [ Default ] For Value 55, Congts! You have Passed in Second Class For Value 85, Congts! You have Passed in First Class **Result:-** Hence the program executed successfully.
default: echo "Your favorite color is neither red, blue, nor green!"; } ?> Output:- For empty Value Your favorite color is neither red, blue, nor green! [Default] For Value red, Your favorite color is red! [Default] For Value blue, Your favorite color is blue! For Value green, Your favorite color is green! Result:- Hence the program executed successfully.
2(b). Write a PHP program to illustrate the use of Looping Statements. Aim:- To write a PHP program to execute Looping statements. Program description:- while - loops through a block of code as long as the specified condition is true do...while - loops through a block of code once, and then repeats the loop as long as the specified condition is true for - loops through a block of code a specified number of times foreach - loops through a block of code for each element in an array PHP – The while Statement. while - loops through a block of code as long as the specified condition is true Syntax:- while ( condition is true ) { code to be executed ; } Source Code:-
"; $x++; } ?> **Output:-** The number is: 1 , The number is: 2 ,The number is: 3 **Result:-** Hence the program executed successfully.
PHP – For Loop. for - loops through a block of code a specified number of times Syntax:- for ( init counter; test counter; increment counter ) { code to be executed; } Source Code:-
"; } ?> **Output:-** The number is: 1 The number is: 2 The number is: 3 The number is: 4 The number is: 5 **Result:-** Hence the program executed successfully.
PHP – For-Each Loop. foreach - loops through a block of code for each element in an array Syntax:- foreach ($ array as $ value ) { code to be executed; } Source Code:-
"; } ?> **Output:-** Red Green Blue Yellow **Result:-** Hence the program executed successfully.
