PHP String Exercises: Get the last three characters of a string
7. Get Last Three Characters
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").
