PHP Alphabet Pattern 23

Here`s a program that prints the above alphabet pattern using PHP Programming:

example.php

Copied

<?php
$alpha = range('A', 'Z');
for($i=4; $i>=0; $i--)
{
 for($j=0; $j<$i; $j++)
  echo "&nbsp;&nbsp;&nbsp;&nbsp;";
 for($j=4; $j>=$i; $j--)
  echo $alpha[$j] . " ";
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

        E
      E D
    E D C
  E D C B
E D C B A

🧠 How the Program Works

Let's break down the logic behind the code:

<?php - This indicates the beginning of a PHP script.
$alpha = range('A', 'Z'); - This line creates an array $alpha containing uppercase letters from 'A' to 'Z'. The range() function generates an array of values within a specified range.
for($i=4; $i>=0; $i--) - This initiates a loop with a variable $i starting from 4 and decreasing by 1 in each iteration until it becomes 0. This loop controls the number of rows in the pattern.
Inside the first loop:
1. for($j=0; $j<$i; $j++) - This nested loop initializes a variable $j to 0 and increments it in each iteration until it is less than $i. This loop prints spaces to create an indentation effect, shifting the subsequent letters to the right in each row.
2. for($j=4; $j>=$i; $j--) - Another nested loop is used here, initializing a variable $j to 4 and decreasing it in each iteration until it becomes greater than or equal to $i. This loop prints the letters in reverse order from the $alpha array, based on the current value of $j.
3. echo $alpha[$j] . " "; - This prints the letter from the $alpha array at index $j and adds a non-breaking space after it. This creates a space between the letters in the pattern.
4. echo "<br>"; - After each row of letters is printed, this statement adds an HTML line break (<br>) to move to the next line.
?> - This marks the end of 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.
