PHP Alphabet Pattern 29

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

example.php

Copied

<?php
$alpha = range('A', 'Z');
$k = 4;
// First Part
for($i=$k; $i>=0; $i--)
{
 for($j=$k; $j>=0; $j--)
 {
  if($j > $i)
   echo "<div>" . $alpha[$j] . "</div>";
  else
   echo "<div>" . $alpha[$i] . "</div>";
 }
 for($j=1; $j<=$k; $j++)
 {
  if($j > $i)
   echo "<div>" . $alpha[$j] . "</div>";
  else
   echo "<div>" . $alpha[$i] . "</div>";
 }
 echo "<br>";
}
// Second Part
for($i=1; $i<=$k; $i++)
{
 for($j=$k; $j>=0; $j--)
 {
  if($j > $i)
   echo "<div>" . $alpha[$j] . "</div>";
  else
   echo "<div>" . $alpha[$i] . "</div>";;
 }
 for($j=1; $j<=$k; $j++)
 {
  if($j > $i)
   echo "<div>" . $alpha[$j] . "</div>";
  else
   echo "<div>" . $alpha[$i] . "</div>";
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

E E E E E E E E E
E D D D D D D D E
E D C C C C C D E
E D C B B B C D E
E D C B A B C D E
E D C B B B C D E
E D C C C C C D E
E D D D D D D D E
E E E E E E E E E

🧠 How the Program Works

Let's break down the logic behind the code:

<?php - This tag indicates the start of PHP code.
$alpha = range('A', 'Z'); - This line creates an array $alpha containing the uppercase letters from 'A' to 'Z'.
$k = 4; - Sets the value of variable $k to 4. This variable controls the size of the pattern.
First Part:
1. The first for loop runs from $k to 0.
2. The nested for loop also runs from $k to 0.
3. Inside the nested loops:
  - If $j (the inner loop variable) is greater than $i (the outer loop variable), it prints the current letter at index $j from the $alpha array inside a <div> element.
  - Otherwise, it prints the letter at index $i from the $alpha array inside a <div> element.
4. After the nested loops, a line break <br> is printed.
Second Part:
1. The second for loop runs from 1 to $k.
2. The nested for loop runs from $k to 0.
3. Inside the nested loops:
  - Similar to the first part, if $j is greater than $i, it prints the letter at index $j from the $alpha array inside a <div> element.
  - Otherwise, it prints the letter at index $i from the $alpha array inside a <div> element.
4. After the nested loops, another line break <br> is printed.
?>- This tag indicates the end of PHP code.

💯 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.
