PHP Alphabet Pattern 16

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

example.php

Copied

<?php
$alpha = range('A', 'Z');
$k = 0;
for($i=0; $i<=4; $i+=2)
{
 for($j=4; $j>=0; $j--)
 {
  if($j > $i)
   echo " &nbsp;";
  else
   echo $alpha[$k++] . " ";
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

    A
  B C D
E F G H I

🧠 How the Program Works

Let's break down the logic behind the code:

<?php: This is the opening tag for a PHP script.
$alpha = range('A', 'Z');: This line creates an array $alpha containing the uppercase letters of the English alphabet, from 'A' to 'Z'.
$k = 0;: Initialize a variable $k to keep track of the index in the $alpha array.
for($i=0; $i<=4; $i+=2): This is the outer loop that iterates from 0 to 4 with a step of 2. It controls the number of rows in the output pattern.
Inside the outer loop:
1. for($j=4; $j>=0; $j--): This is the inner loop that iterates from 4 to 0. It controls the number of columns and the spaces within each row.
2. Inside the inner loop:
  - if($j > $i): This condition checks if the value of $j (column index) is greater than $i (row index). If true, it prints a space to create an indentation.
  - else: If the above condition is false, it means we've reached the point where a letter should be printed.
    - echo $alpha[$k++] . " ";: This line prints the current letter from the $alpha array using the index $k, and then increments the index $k. It also adds a space after each letter.
echo "<br>";: This line prints an HTML line break (<br>) to move to the next line after each row of letters.
?>: This is the closing tag for the PHP script.

💯 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.
