Last update on December 20 2024 10:19:32 (UTC/GMT +8 hours)

Write a PHP script to print letters from 'a' to 'z'.

Visual Presentation:

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.
