PHP Alphabet Pattern 25

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

example.php

Copied

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

💻 Testing the Program

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

Output

A B C D E
F G H I
J K L
M N
O

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with opening <?php tag.
$alpha = range('A', 'Z');: This line creates an array $alpha containing letters from 'A' to 'Z'. So, $alpha will be an array like ['A', 'B', 'C', ..., 'Z'].
$k = 0;: Initialize a counter variable $k to 0. This variable will be used to index the $alpha array.
for($i=0; $i<=4; $i++): This is the outer loop that iterates 5 times (0 to 4) for the rows of the output pattern.
Inside the outer loop, we have another loop: for($j=4; $j>=$i; $j--). This inner loop iterates from 4 down to the current value of $i. This loop controls the number of characters printed in each row.
echo $alpha[$k++] . " ";: Inside the inner loop, this line outputs the character at the index $k of the $alpha array, followed by a space. It then increments $k by 1. So, in the first iteration of the inner loop, it outputs 'A', in the second iteration, 'B', and so on.
After the inner loop completes, echo "<br>"; is used to output a line break, creating a new line for the next row.
The outer loop continues to execute, and with each iteration, the inner loop outputs one more character from the $alpha array and moves to the next line.
Finally, when both loops complete, the program ends with the closing ?> tag.

💯 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.
