PHP Alphabet Pattern 28

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

example.php

Copied

<?php
$alpha = range('A', 'Z');
$k = 4;
for($i=$k; $i>=0; $i--)
{
 for($j=$k; $j>=0; $j--)
 {
  if($j > $i)
   echo "<div>" . $alpha[$j] . "</div>";
  else
   echo "<div>" . $alpha[$i] . "</div>";
 }
 for($j=1; $j<=$k; $j++)
 {
  if($j > $i)
   echo "<div>" . $alpha[$j] . "</div>";
  else
   echo "<div>" . $alpha[$i] . "</div>";
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

E E E E E E E E E
E D D D D D D D E
E D C C C C C D E
E D C B B B C D E
E D C B A B C D E

🧠 How the Program Works

Let's break down the logic behind the code:

$alpha = range('A', 'Z');: This line creates an array $alpha containing the uppercase letters of the English alphabet from 'A' to 'Z'.
$k = 4;: The variable $k is assigned the value 4.
for($i=$k; $i>=0; $i--): This starts a loop where the variable $i is initialized to the value of $k (which is 4), and the loop continues as long as $i is greater than or equal to 0. In each iteration, $i is decremented by 1.
The first nested for loop: for($j=$k; $j>=0; $j--): This is a nested loop within the first loop. It iterates over the variable $j, starting from the value of $k and going down to 0. In each iteration of this loop, the program does the following:
1. if($j > $i): This condition checks if $j is greater than $i.
  - If true, it prints a <div> element containing the letter at index $j in the $alpha array.
  - If false, it prints a <div> element containing the letter at index $i in the $alpha array.
The second nested for loop: for($j=1; $j<=$k; $j++): This is another nested loop within the first loop. It iterates over the variable $j, starting from 1 and going up to the value of $k. In each iteration of this loop, the program does the following:
1. if($j > $i): This condition checks if $j is greater than $i.
  - If true, it prints a <div> element containing the letter at index $j in the $alpha array.
  - If false, it prints a <div> element containing the letter at index $i in the $alpha array.
echo "<br>";: After both nested loops finish executing, this line prints an HTML line break (<br>) to move to the next line in the output.
The outer loop continues for the next iteration with the value of $i decremented by 1, and the process repeats until $i becomes less than 0.

💯 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.
