PHP String Exercises: Print the next character of a specific character

Sample character : 'a'
Sample character : 'z'

Sample Solution:

PHP Code:

<?php
$cha = 'a';
$next_cha = ++$cha; 
//The following if condition prevent you to go beyond 'z' or 'Z' and will reset to 'a' or 'A'.
if (strlen($next_cha) > 1) 
{
 $next_cha = $next_cha[0];
 }
echo $next_cha."\n";
?>

Output:

Explanation:

The above PHP code snippet increments a character stored in the variable '$cha' to the next character in the ASCII sequence using the pre-increment operator '++$cha'. It then checks if the resulting string length is greater than 1, which would occur if the character overflows beyond 'z' or 'Z'. If so, it resets the character to 'a' or 'A'. Finally, it outputs the next character.
