PHP Alphabet Pattern 17

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

💻 Testing the Program

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

Output

EDCB*
EDC*A
ED*BA
E*CBA
*DCBA

🧠 How the Program Works

Let's break down the logic behind the code:

$alpha = range('A', 'Z');: This line creates an array $alpha containing uppercase letters from 'A' to 'Z'.
$k = 0;: This line initializes a variable $k with the value 0. However, $k is not used anywhere in the given code.
The program enters an outer loop: for($i=0; $i<=4; $i++). This loop iterates from 0 to 4.
Inside the outer loop, there is an inner loop: for($j=4; $j>=0; $j--). This loop iterates from 4 to 0.
The program then checks if the inner loop counter $j is equal to the outer loop counter $i: if($j == $i). If this condition is true, it prints an asterisk *, indicating the diagonal of asterisks in the output pattern.
If the condition is false, it prints the letter corresponding to the current value of $j from the $alpha array. This is why the letters from 'Z' to 'A' are printed in a diagonal pattern.
After each inner loop iteration, a <br> tag is printed to create a line break in the output, which starts a new line for the next row of characters.
The outer loop continues to the next iteration, and the process is repeated until the outer loop counter $i reaches 4.
The final output of the program is a diagonal pattern of letters from 'Z' to 'A', with an asterisk (*) on the diagonal line.

💯 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.
