PHP Alphabet Pattern 31

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=0; $j<=4; $j++)
 {
  if($i == $j)
   echo $alpha[$j];
  else  
   echo "&nbsp;&nbsp;";
 }
 for($k=3; $k>=0; $k--)
 {
  if($i == $k)
   echo $alpha[$k];
  else
   echo "&nbsp;&nbsp;";
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

A       A
 B     B
  C   C
   D D
    E

🧠 How the Program Works

Let's break down the logic behind the code:

$alpha = range('A', 'Z');: This line creates an array $alpha containing the uppercase letters of the English alphabet from 'A' to 'Z'.
for($i=0; $i<=4; $i++): This is the outer loop that iterates from 0 to 4 (inclusive). It controls the rows of the pattern.
Inside the outer loop, there are two nested loops:
1. for($j=0; $j<=4; $j++): The first nested loop iterates from 0 to 4 (inclusive). It controls the columns within the left half of the pattern.
2. for($k=3; $k>=0; $k--): The second nested loop iterates from 3 to 0 (inclusive). It controls the columns within the right half of the pattern.
The pattern is generated using conditional statements inside the loops:
1. if($i == $j): This condition checks if the current row index $i is equal to the current column index $j. If true, it prints the corresponding letter from the $alpha array.
2. else: If the above condition is false, it prints two non-breaking spaces ( ) to create a visual gap.
3. Similarly, the second nested loop uses the condition if($i == $k) to print letters in the right half of the pattern.
After each row is generated, echo "<br>"; is used to insert a line break, moving to the next row.

💯 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.
