PHP Alphabet Pattern 10

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 $alpha[$i];
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

E
DD
CCC
BBBB
AAAAA

🧠 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 creates an array $alpha containing the letters from 'A' to 'Z'. So, $alpha[0] will hold 'A', $alpha[1] will hold 'B', and so on.
for($i=4; $i>=0; $i--): This is an outer loop that initializes $i to 4 and then iterates as long as $i is greater than or equal to 0. It decrements $i by 1 in each iteration.
Inside the outer loop, an inner loop is started with for($j=4; $j>=$i; $j--). This inner loop initializes $j to 4 and iterates as long as $j is greater than or equal to the current value of $i. It decrements $j by 1 in each iteration.
Inside the inner loop, echo $alpha[$i]; is executed. It prints the letter at index $i from the $alpha array. Since the array contains letters from 'A' to 'Z', and $i is decreasing from 4 to 0, this means that the same letter will be printed $i+1 times.
After the inner loop completes, echo "<br>"; is used to print a line break. This creates a new line after each set of letters.
The inner loop continues its iterations until $j is no longer greater than or equal to $i. Once the inner loop completes, the outer loop continues to the next iteration, decrementing $i by 1.
Steps 4-7 are repeated until the outer loop completes its iterations.
?>: This marks the end of the PHP code block.

💯 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.
