Advance Features of PHP - (BCA / B.Tech)

Advance Features PHP in Hindi | Advanced Features of PHP in Hindi:

The use of a semicolon in PHP is to separate each statement and its correct use makes the code organized and error-free.

The forgiving nature of PHP makes it easy in programming, but for good practice, the correct coding style should be adopted.

1. The "Forgiving" Nature of PHP:

PHP is called a "Forgiving Language". This means that PHP easily handles small mistakes and does not stop running the script.

Forgiving features of PHP:

Lack of declaration: In PHP, it is not necessary to declare variables in advance. You can use variables directly.

<?php

$name = "Amit"; // The variable was used directly

echo $name;

Automatic management of data types:

In PHP, you do not have to declare data types for variables. PHP itself recognizes the type.

<?php

$age = 25; // Integer

$name = "Amit"; // String

echo $age . " " . $name;

Forgiving minor syntax errors:

If you have made a small mistake, such as using the wrong type of variable, PHP will give you a notice but will continue to work instead of stopping the entire script.

<?php

$num = "5"; // String

echo $num + 10; // PHP will convert this to 15

Missing file or wrong function:

If you have included a file that does not exist or have written a wrong function, PHP will only give a notice.

<?php

include("missing_file.php"); // Will give a warning but the script will run

echo "This line will run!";

Importance of the forgiving nature of PHP:

Easy for beginners: PHP makes it simple for new programming learners.
The script does not stop: The code continues to work even if there are small mistakes.
Dynamic website: A dynamic website can be created even by writing less code.

2. Use of Semicolon in PHP

In PHP, a semicolon (;) is used at the end of every statement. This helps PHP to understand where one statement is ending and the next one is starting.

Importance of Semicolon in PHP in Hindi | Importance of semicolon:

To indicate the end of a statement:A line of code in PHP is considered complete only when there is a semicolon at the end of it.

<?php

echo "Hello World!"; // A semicolon is necessary

To make the code readable: A semicolon makes the code easy to read and understand.
To separate multiple statements: If there are more than one statements, a semicolon differentiates between them.

<?php

$name = "Amit";

echo "Hello " . $name; // First statement

echo "Welcome to PHP!"; // Second statement

Problem if a semicolon is not used: If you forget to put a semicolon, a syntax error can occur in PHP.

<?php

echo "Hello World" // There is no semicolon here, it will give an error

echo "Welcome to PHP!";

If a semicolon is not necessary: In some special cases, a semicolon is not necessary, such as:

If there is only one statement inside an if or while and the code block is in { }.

<?php

if (true) {

echo "This will work!"; // It is in a block, so it is correct

}

Rules:

Put a semicolon at the end of every statement.
Lack of a semicolon can break the code.
