19. Arithmetic on Character Variables

Arithmetic operations on character variables : $d = 'A00'. Using this variable print the following numbers.

Sample Solution: -

PHP Code:

<?php
// Initialize variable $d with value 'A00'
$d = 'A00';

// Loop through 5 iterations
for ($n = 0; $n < 5; $n++) {
    // Increment $d and echo the result
    echo ++$d . "\n";
}
?>

Explanation:

• Initialize Variable:
• $d is initialized with the string value 'A00'.
• Loop through 5 Iterations:
• A for loop iterates 5 times, with $n starting at 0 and incrementing by 1 until it reaches 4.
• Increment and Display:
• In each iteration, ++$d increments $d in "alphanumeric" order.
• The echo statement outputs the incremented value of $d, followed by a newline (\n).
• Output Explanation:
• Each increment follows a pattern similar to an alphanumeric sequence. For example, starting with 'A00', it will output values like A01, A02, A03, A04, and A05.

Output:

A01                                                         
A02                                                         
A03                                                         
A04                                                         
A05

• Write a PHP script to perform addition on a string with embedded numbers while retaining its alphabetic prefix.
• Write a PHP script to develop a function that increments the numeric part of an alphanumeric string and formats the result.
• Write a PHP script to simulate arithmetic operations on a string by adding a fixed value and outputting a new formatted string.
