PHP String Exercises: Get the last three characters of a string

PHP String: Exercise-7 with Solution

Write a PHP script to get the last three characters of a string.

Sample String : '[email protected]'

Visual Presentation:

Sample Solution:

PHP Code:

<?php
$str1 = '[email protected]';   // Assigns an email address to the variable $str1
echo substr($str1, -3)."\n";  // Extracts the last 3 characters from $str1 and echoes them
?>

Output:

com

Explanation:

In the exercise above,

• Defines a string variable '$str1' containing the value '[email protected]'. This variable holds an email address.
• Uses the "substr()" function to extract the last 3 characters from the string stored in '$str1'. The "substr()" function takes two parameters: the string to extract from ($str1), and the starting position of the substring (-3, indicating the third character from the end of the string).
• Echoes the extracted substring to the output, followed by a newline character ("\n").
