PHP Alphabet Pattern 4

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=$i; $j>=0; $j--)
  echo $alpha[$j];
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

A
BA
CBA
DCBA
EDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

<?php and ?>: These are PHP tags that indicate the beginning and end of PHP code.
$alpha = range('A', 'Z');: This line creates an array called $alpha containing uppercase English letters from 'A' to 'Z'. So, $alpha[0] would be 'A', $alpha[1] would be 'B', and so on.
for($i=0; $i<=4; $i++): This is the outer loop that iterates from 0 to 4. It controls the number of lines in the pattern. In this case, there will be 5 lines.
{: Opening brace for the outer loop.
for($j=$i; $j>=0; $j--): This is the inner loop that iterates from the value of $i (which corresponds to the current line number) down to 0. It controls the number of characters printed on each line.
echo $alpha[$j];: This line prints the character at index $j from the $alpha array. The character printed on each line will be in descending order.
echo "<br>";: This line prints an HTML line break (<br>) tag after each inner loop iteration, which moves the output to the next line.
}: Closing brace for the inner loop.
}: Closing brace for the outer loop.

💯 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.
