Features of C# 14.0 🧩 1️⃣ Field-backed Properties (0:40 – 1:00) Pehla feature hai — Field-backed Properties Ab aapko manually private field likhne ki zarurat nahi. C# 14 mein ek naya contextual keyword aaya hai — field public string Name { get ; set => field = value ?? throw new ArgumentNullException( nameof ( value )); } Yahaan field compiler-generated backing field ko represent karta hai. Validation ya logic likhna ab super easy ho gaya hai! 🧩 2️⃣ Extension Members (1:00 – 1:25) Dusra feature — Extension Members Pehle hum sirf extension methods bana sakte the, ab hum properties , events , aur static members bhi extend kar sakte hain! public static class StringExtensions { public static int WordCount ( this string str) => str.Split( ' ' ).Length; } Ab koi bhi string par .WordCount() laga ke result le sakte ho — reusability aur readability dono badh gayi! 💪 🧩 3️⃣ Null-Conditional Assignment (1:25 – 1:50) ...

LAMP is specially for LINUX (L--> LINUX,A---> Apache,M--> MYSQL,P-->PHP)
MAMP is specially for MAC (M-->MAC,A--> Apache,M-->MYSQL,P---> PHP)

2) Open XAMPP Control Panel:-
Click on the Desktop xampp icon and click on the apache start button
if not present in desktop icon then go c://xampp/xampp-control.exe
3) open notepad and create .php file
2) Open XAMPP Control Panel:-
Click on the Desktop xampp icon and click on the apache start button
if not present in desktop icon then go c://xampp/xampp-control.exe
3) open notepad and create .php file
under c:/xampp/htdocs/foldername (create new folder first time and save file)
<?php
echo "hello world";
?>
save php file using .php extension
4) open browser and type localhost/folder name
echo "hello world";
?>
save php file using .php extension
4) open browser and type localhost/folder name
Internal Working of PHP:-
When we click on a file or direct URL from the browser address bar then it will create HttpRequest Object and Send to Apache Web Server.
Apache Web Server will get requests, process the requested file, generate a result, convert the result into HTML form and send it back to the browser using HttpResponse Object.
Url locate Server Address using localhost or remote server.
for example, http://localhost/php11/Demo1.php is a localhost URL for testing purposes or a desktop-based web application.
for example http://shivaconceptsolution.com/digital/ It is the remote URL because shivaconceptsolution.com is a domain name that points to a remote server
Example of PHP:-
Create Hello World Program?
<?php
print("hello world");
?>
Create Welcome Program?
<html>
<head>
<body bgcolor='cyan'>
<h1>Second Program of PHP</h1>
<hr>
<?php
print("PHP IS A SCRIPT<br>");
print("WELCOME IN SCS<br>");
print("Hello");
?>
</body>
</html>
Create Addition Program:-
<?php
$a=1555656777;
$b=2345555555;
$c=$a+$b;
print($c);
?>
ASSIGNMENT:-
1) WAP to swap two numbers?
2) WAP to calculate simple interest?
<?php
$p=15000;
$r=2.2;
$t=3;
$si = ($p*$r*$t)/100;
echo "Result is ".$si;
?>
3) WAP to calculate the area of triangle or rectangle?
