PHP Alphabet Pattern 2

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=4; $j>=$i; $j--)
  echo $alpha[$j];
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

E
ED
EDC
EDCB
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

<?php: This indicates the start of a PHP code block.
$alpha = range('A', 'Z');: This line creates an array named $alpha containing the uppercase letters from 'A' to 'Z'. So, after this line, $alpha will contain ['A', 'B', 'C', ..., 'Z'].
for ($i = 4; $i >= 0; $i--) {: This is the start of the outer loop. It initializes a variable $i to 4 and then iterates as long as $i is greater than or equal to 0. In each iteration, it decreases the value of $i by 1.
for ($j = 4; $j >= $i; $j--) {: This is the start of the inner loop. It initializes a variable $j to 4 and then iterates as long as $j is greater than or equal to the current value of $i. In each iteration, it decreases the value of $j by 1.
echo $alpha[$j];: Inside the inner loop, this line prints the letter at the index $j from the $alpha array. Initially, $j is 4, so it prints the letter 'E'. In the next iteration, it prints 'D', and so on, until it prints the letter corresponding to the current value of $i.
echo "<br>";: After the inner loop completes, this line outputs an HTML line break tag, which moves the output to the next line.
The inner loop continues until $j becomes equal to the current value of $i. After that, the control returns to the outer loop.
The outer loop then proceeds to the next iteration, and the value of $i decreases by 1.
Steps 3-7 repeat until the outer loop completes all iterations, which are from 4 to 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.
