PHP Alphabet Pattern 9

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

💻 Testing the Program

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

Output

A
BB
CCC
DDDD
EEEEE

🧠 How the Program Works

Let's break down the logic behind the code:

<?php: This opening tag indicates the beginning of a PHP script.
$alpha = range('A', 'Z');: This line creates an array called $alpha that contains all uppercase English letters from 'A' to 'Z'. The range() function is used to generate a sequence of values.
for($i=0; $i<=4; $i++): This is the outer loop that iterates from 0 to 4. It's responsible for controlling the number of rows in the output.
Inside the outer loop, you have another loop:
- for($j=0; $j<=$i; $j++): This inner loop iterates from 0 to the current value of $i. It's responsible for printing the letters in each row.
echo $alpha[$i];: This line prints the letter at the index $i from the $alpha array. Since $i represents the row number, it prints the same letter multiple times in the same row.
echo "<br>";: This line outputs an HTML line break (<br>) tag, which moves the output to the next line, creating the effect of each row being on a new line.
After the inner loop finishes, the outer loop increments $i and the process continues until $i reaches 4 (the outer loop condition).
The program ends with ?>, which closes 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.
