PHP Alphabet Pattern 5

Here`s a program that prints the above alphabet pattern using PHP Programming:

example.php

Copied

<?php
$alpha = range('A', 'Z');
for($i=4; $i>=0; $i--)
{
 for($j=0; $j<=$i; $j++)
  echo $alpha[$j];
 echo "<br>";
}
?>

💻 Testing the Program

When you run the above program, it will print the following output:

Output

ABCDE
ABCD
ABC
AB
A

🧠 How the Program Works

Let's break down the logic behind the code:

$alpha = range('A', 'Z');: This line creates an array $alpha containing uppercase English letters from 'A' to 'Z'. So, $alpha will be an array like: ['A', 'B', ..., 'Z'].
for($i=4; $i>=0; $i--) {: This outer loop runs five times, decrementing the value of $i from 4 to 0. Each iteration of this loop represents a row in the triangular pattern.
for($j=0; $j<=$i; $j++) {: This inner loop runs from 0 to the value of $i, inclusive. It represents the number of letters to be printed in the current row. For the first row, $i will be 4, so the inner loop will run from 0 to 4.
echo $alpha[$j];: This line prints the letter at the index $j of the $alpha array. In the first iteration of the inner loop, it will print 'A', then 'B', and so on, until it prints the letter corresponding to the value of $i.
echo "<br>";: After printing the letters in the current row, this line adds an HTML line break (<br>) to move to the next line.
}: Closes the inner loop.
}: Closes the outer loop.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
