PHP Alphabet Pattern 26

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=0; $i<=4; $i++)
{
 for($j=$i; $j<=4; $j++)
  echo $alpha[$j];
 for($k=$i; $k>0; $k--)
  echo $alpha[$k-1]; 
 echo "<br>";
}
?>

💻 Testing the Program

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

Output
ABCDE
BCDEA
CDEBA
DECBA
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

  1. <?php - This indicates the start of a PHP code block.
  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. $k = 0; - Initialize the variable $k with the value 0.
  4. for($i=0; $i<=4; $i++) - This is the outer loop that iterates from 0 to 4. The variable $i is used to control the number of letters displayed in each row.
  5. for($j=$i; $j<=4; $j++) - This is the first nested loop. It starts from the current value of $i and goes up to 4. It's responsible for printing the first part of each row, which consists of letters in increasing order.
  6. echo $alpha[$j]; - This line prints the letter at index $j from the $alpha array, which corresponds to the current letter to be displayed.
  7. for($k=$i; $k>0; $k--) - This is the second nested loop. It starts from the current value of $i and goes down to 1. It's responsible for printing the second part of each row, which consists of letters in decreasing order.
  8. echo $alpha[$k-1]; - This line prints the letter at index $k-1 from the $alpha array, which corresponds to the current letter to be displayed in reverse order.
  9. echo "<br>"; - This line prints an HTML line break (<br>) to move to the next line after each row is completed.
  10. } - Closing the inner loop.
  11. } - Closing the outer loop.
  12. ?> - This indicates 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.
