PHP String Exercises: Print letters from 'a' to 'z'

Sample Solution:

PHP Code:

<?php
for ($x = ord('a'); $x <= ord('z'); $x++)
// Loop through ASCII values of lowercase letters from 'a' to 'z'.

 echo chr($x);
// Convert ASCII value to corresponding character and echo.

 echo "\n";
// Output newline character.
?>

Sample Output:

abcdefghijklmnopqrstuvwxyz

Explanation:

The above PHP code snippet generates and echoes all lowercase letters from 'a' to 'z' using ASCII values:

The "for" loop iterates through ASCII values of lowercase letters from 'a' to 'z'.
ord('a') returns the ASCII value of 'a', and ord('z') returns the ASCII value of 'z'.
Inside the loop, chr($x) converts each ASCII value back to its corresponding character and echoes it.
After the loop, echo "\n"; outputs a newline character to format the output.

So, the output of this code would be all lowercase letters from 'a' to 'z' on a single line.
