How to resolve the algorithm Hello world/Text step by step in the PHP programming language

Problem Statement

Display the string Hello world! on a text console.

Let's start with the solution:

The given PHP code is a simple program that prints the message "Hello world!" to the console.

Code Breakdown:

The first line of the code, <?php, is the opening PHP tag, which tells the PHP interpreter to begin interpreting the code within it.
echo "Hello world!\n" is an echo statement that prints the string "Hello world!" to the console. The \n character at the end of the string represents a newline, which moves the cursor to the next line after printing the message.
The last line of the code, ?>, is the closing PHP tag, which tells the PHP interpreter to stop interpreting the code after it.

Output:

When you run this code, it will print the following output to the console:

Hello world!

Explanation of the Code:

The echo statement is used to print data to the console. In this case, it is used to print the string "Hello world!".
The \n character at the end of the string represents a newline, which means that after printing "Hello world!", the cursor will move to the next line.
The PHP tags (<?php and ?>) are used to mark the beginning and end of PHP code within an HTML document.

Additional Notes:

The echo statement can be used to print any type of data, including strings, numbers, and variables.
Newlines can be added to output using the \n character.
PHP code can be embedded within HTML documents using the PHP tags.

<?php
echo "Hello world!\n";
?>

Hello world!
