PHP Alphabet Pattern 18

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=0; $j<=$i; $j++)
  echo $alpha[$j];
 for($k=$i-1; $k>=0; $k--)
  echo $alpha[$k];
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

A
ABA
ABCBA
ABCDCBA
ABCDEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

<?php - This is the opening tag that indicates the start of PHP code.
$alpha = range('A', 'Z'); - This line creates an array $alpha containing the letters from 'A' to 'Z'. This array will be used to print the letters.
$k = 0; - Initializes a variable $k with the value 0.
for($i=0; $i<=4; $i++) - This is the outer loop that runs from 0 to 4 (inclusive). It controls the number of rows in the pyramid.
1. Inside the outer loop, for($j=0; $j<=$i; $j++) - This is the inner loop that runs from 0 to the current value of $i. It controls the number of letters printed in each row.
  - echo $alpha[$j]; - Prints the letter from the $alpha array at index $j.
2. After the inner loop, for($k=$i-1; $k>=0; $k--) - This loop runs in reverse from the current value of $i minus 1 down to 0. It prints the letters in reverse order.
  - echo $alpha[$k]; - Prints the letter from the $alpha array at index $k.
3. echo "<br>"; - Prints an HTML line break (<br>) to move to the next line after each row of letters.
?> - This is the closing tag that indicates the end of PHP code.

💯 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.
