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:

Output

    A
   B B
  C   C
 D     D
E       E

🧠 How the Program Works

Let's break down the logic behind the code:

<?php ... ?>: This is the opening and closing tag of PHP, indicating that the following code contains PHP instructions.
$alpha = range('A', 'Z');: This line creates an array $alpha containing the uppercase English letters from 'A' to 'Z'.
for($i=0; $i<=4; $i++): This is the outer loop that iterates from 0 to 4. It controls the rows of the pattern.
for($j=4; $j>=0; $j--): This is the first nested loop that iterates from 4 to 0. It controls the columns before the center of the pattern.
Inside the nested loop:
- if($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 $alpha array.
- If the condition is false, it echoes an HTML <div> with a non-breaking space ( ) to create an empty space.
for($k=1; $k<=4; $k++): This is the second nested loop that iterates from 1 to 4. It controls the columns after the center of the pattern.
Inside the second nested loop:
- if($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 ( ) to create an empty space.
echo "<br>";: This line adds an HTML line break (<br>) after each row of the pattern to move to the next line.
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.
The final pattern will look like a diamond, with letters from 'A' to 'Z' forming the outline of the diamond and empty spaces ( ) filling the inside.
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.
