PHP Alphabet Pattern 32

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

example.php
Copied
Copy To Clipboard
<?php
$alpha = range('A', 'Z');
for($i=0; $i<=4; $i++)
{
 for($j=4; $j>=$i; $j--)
  echo "<div>&nbsp;</div>";
 for($k=0; $k<=$i; $k++)
  echo "<div>" . $alpha[$k] . "</div>";
 $n = $k - 1;
  for($m=0; $m<$i; $m++)
 echo "<div>" . $alpha[--$n] . "</div>";
 echo "<br>";
}
?>

💻 Testing the Program

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

Output
    A
   ABA
  ABCBA
 ABCDCBA
ABCDEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

  1. <?php and ?>: These tags indicate the beginning and end of PHP code.
  2. $alpha = range('A', 'Z');: This line creates an array $alpha containing all the uppercase letters of the English alphabet from 'A' to 'Z'.
  3. for($i=0; $i<=4; $i++): This is the outer loop that controls the number of rows in the pattern. It runs for 5 iterations (0 to 4).
  4. Inner Loop 1 (for($j=4; $j>=$i; $j--)):
    • This loop generates a series of empty div elements to create the left indentation of the pattern.
    • The number of empty div elements decreases with each iteration of the outer loop.
  5. Inner Loop 2 (for($k=0; $k<=$i; $k++)):
    • This loop generates a series of div elements containing the letters of the alphabet from 'A' to the current index $i.
    • The number of div elements with letters increases with each iteration of the outer loop.
  6. $n = $k - 1;: This line stores the value of $k - 1 in the variable $n. This value will be used later in the third inner loop.
  7. Inner Loop 3 (for($m=0; $m<$i; $m++)):
    • This loop generates a series of div elements containing the letters of the alphabet in reverse order.
    • The number of div elements with reversed letters decreases with each iteration of the outer loop.
  8. echo "<br>";: This line prints a line break to move to the next row after each iteration of the outer loop.

💯 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.
