PHP Alphabet Pattern 15

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

example.php
Copied
Copy To Clipboard
<?php
$alpha = range('A', 'Z');
$k = 0;
for($i=4; $i>=0; $i--)
{
 for($j=0; $j<=$i; $j++)
  echo $alpha[$j];
 for($k=$i; $k<4; $k++)
  echo "<div>*</div><div>*</div>";
 for($m=$i; $m>=0; $m--)
  echo "<div>" . $alpha[$m] . "</div>";
 echo "<br>";
}
?>

💻 Testing the Program

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

Output
ABCDEEDCBA
ABCD**DCBA
ABC****CBA
AB******BA
A********A

🧠 How the Program Works

Let's break down the logic behind the code:

  1. The range() function generates an array $alpha containing uppercase letters from 'A' to 'Z'.
  2. The variable $k is initialized to 0.
  3. An outer loop (for($i=4; $i>=0; $i--)) runs five times, decrementing the value of $i from 4 to 0. This loop controls the number of rows in the output.
  4. Inside the outer loop, there are three inner loops:
    1. Inner loop 1 (for($j=0; $j<=$i; $j++)) prints the letters from the $alpha array. The loop iterates from 0 to the current value of $i, printing the corresponding letter at index $j from the $alpha array.
    2. Inner loop 2 (for($k=$i; $k<4; $k++)) prints two div elements with "*", and it runs 5 - $i times. This loop is used to create the central portion of each row.
    3. Inner loop 3 (for($m=$i; $m>=0; $m--)) prints the letters from the $alpha array in reverse order. The loop iterates from the current value of $i to 0, printing the corresponding letter at index $m from the $alpha array.
  5. After each iteration of the inner loops, echo "<br>"; is used to print a line break, creating a new line for the next row.
  6. The outer loop continues to execute until $i reaches 0, generating a pattern where letters are printed in different orders, and the central portion of each row contains "*", surrounded by div elements.
  7. The output will be a pattern that resembles a pyramid-like structure, with letters and "*" arranged in a specific order.

💯 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.
