PHP Alphabet Pattern 7

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=$i; $j>=0; $j--)
  echo $alpha[$j];
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

EDCBA
DCBA
CBA
BA
A

🧠 How the Program Works

Let's break down the logic behind the code:

$alpha = range('A', 'Z');: This line creates an array $alpha containing capital letters from 'A' to 'Z'.
for ($i = 4; $i >= 0; $i--) {: This initiates an outer loop that iterates five times, starting from $i with a value of 4 and decrementing it by 1 in each iteration until it becomes 0.
for ($j = $i; $j >= 0; $j--) {: Inside the outer loop, an inner loop is initiated. It iterates from the current value of $i down to 0, and the variable $j is used as the loop counter.
echo $alpha[$j];: Within the inner loop, this line outputs the character at index $j from the $alpha array. As the inner loop progresses, it outputs characters in reverse order based on the current value of $j.
echo "<br>";: After the inner loop completes, this line outputs an HTML line break <br>, causing the next characters to be displayed on a new line.
The inner loop continues to execute until $j becomes 0, outputting characters in reverse order.
After the inner loop completes, the outer loop moves to the next iteration with a decreased value of $i, and the process repeats.
The outer loop continues to execute until $i becomes 0, generating a pyramid-like pattern of characters on each line.
The program completes when the outer loop finishes execution.

💯 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.
