PHP Alphabet Pattern 33

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

example.php

Copied

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

💻 Testing the Program

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

    A
   B B
  C   C
 D     D
E       E

🧠 How the Program Works

Let's break down the logic behind the code:

1. <?php ... ?>: This is the opening and closing tag of PHP, indicating that the following code contains PHP instructions.
2. $alpha = range('A', 'Z');: This line creates an array $alpha containing the uppercase English letters from 'A' to 'Z'.
3. for($i=0; $i<=4; $i++): This is the outer loop that iterates from 0 to 4. It controls the rows of the pattern.
4. for($j=4; $j>=0; $j--): This is the first nested loop that iterates from 4 to 0. It controls the columns before the center of the pattern.
5. Inside the nested loop:
   • if($i == $j): This condition checks if the current row $i is equal to the current column $j.
   • If the condition is true, it echoes an HTML <div> containing the corresponding letter from the $alpha array.
   • If the condition is false, it echoes an HTML <div> with a non-breaking space (&nbsp;) to create an empty space.
6. for($k=1; $k<=4; $k++): This is the second nested loop that iterates from 1 to 4. It controls the columns after the center of the pattern.
7. Inside the second nested loop:
   • if($i == $k): This condition checks if the current row $i is equal to the current column $k.
   • If the condition is true, it echoes an HTML <div> containing the corresponding letter from the $alpha array.
   • If the condition is false, it echoes an HTML <div> with a non-breaking space (&nbsp;) to create an empty space.
8. echo "<br>";: This line adds an HTML line break (<br>) after each row of the pattern to move to the next line.
9. The two nested loops within the outer loop create the left and right halves of the pattern, forming a diamond shape with letters from the $alpha array.
10. The final pattern will look like a diamond, with letters from 'A' to 'Z' forming the outline of the diamond and empty spaces (&nbsp;) filling the inside.
11. The program outputs the generated HTML code, which, when rendered in a web browser, displays the diamond pattern.

💯 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.
