PHP Alphabet Pattern 22

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 "<div>&nbsp;</div>";
  else
   echo "<div>" . $alpha[$k++] . "</div>";
 }
 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 J
K L M N O

🧠 How the Program Works

Let's break down the logic behind the code:

$alpha = range('A', 'Z');: This line initializes an array called $alpha containing uppercase English letters from 'A' to 'Z'. This array will be used to populate the alphabets in the pattern.
$k = 0;: This initializes a variable $k to keep track of the index of the $alpha array.
The outer loop: for($i=0; $i<=4; $i++): This loop runs from 0 to 4 (inclusive) and represents the rows of the pattern.
The inner loop: for($j=4; $j>=0; $j--): This loop runs from 4 to 0 (inclusive) and represents the columns of the pattern.
Inside the inner loop, there is an if condition:
- if($j > $i): If the column index $j is greater than the row index $i, it means we're in the upper triangle area of the pattern, and a non-breaking space ( ) wrapped in a <div> is echoed to create empty spaces.
- else: Otherwise, if the column index is less than or equal to the row index, an alphabet character is displayed using the $alpha array, and the index $k is incremented.
echo "<br>";: After each row is generated and the inner loop completes, a line break <br> is echoed to move to the next line in the output.

💯 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.
