PHP Alphabet Pattern 20

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=4; $j>=0; $j--)
 {
  if($j > $i)
   echo "<div>&nbsp;</div>";
  else
   echo "<div>" . $alpha[$j] . "</div>"; 
 }
 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: This opening tag indicates the start of a PHP code block.
$alpha = range('A', 'Z');: This line creates an array called $alpha containing the uppercase letters of the English alphabet from 'A' to 'Z'.
for($i=0; $i<=4; $i++): This initiates a for loop that will iterate five times, with the variable $i starting from 0 and increasing by 1 in each iteration, until it reaches 4.
Inside the outer loop:
- for($j=4; $j>=0; $j--): This initiates an inner for loop that will iterate five times, with the variable $j starting from 4 and decreasing by 1 in each iteration, until it reaches 0.
Inside the nested loops:
- if($j > $i): This is a conditional statement that checks whether the value of $j is greater than the value of $i. If this condition is true, it executes the following line.
- echo "<div> </div>";: If the condition is true, this line outputs an empty <div> element, which is used to create vertical space.
- else: If the condition in the if statement is false, this block of code is executed.
- echo "<div>" . $alpha[$j] . "</div>";: This line outputs a <div> element containing the letter from the $alpha array at the index $j. The index of $alpha corresponds to the current value of $j.
echo "<br>";: After the inner loop finishes executing, this line outputs a line break <br> element, moving the output to the next line.
After the outer loop and its nested loops complete, the program ends execution.

💯 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.
