PHP Number Pattern 13

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

example.php

Copied

<?php
for($i=5; $i>=1; $i--)
{
 if($i%2 == 0)
 {
  for($j=$i; $j>=1; $j--)  
   echo $j; 
 }
 else
 {
  for($j=1; $j<=$i; $j++)
   echo $j;
 }
 echo "<br>"; 
}
?>

💻 Testing the Program

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

🧠 How the Program Works

Let's break down the logic behind the code:

<?php - This is the opening tag of a PHP script, indicating the start of PHP code execution.
for($i=5; $i>=1; $i--) - This is an outer for loop that initializes a variable $i with the value 5. The loop runs as long as $i is greater than or equal to 1, and in each iteration, $i is decremented by 1.
Inside the outer loop, there is an if statement that checks whether $i is even ($i % 2 == 0):
1. If $i is even:
  - for($j=$i; $j>=1; $j--) - This is an inner for loop that initializes a variable $j with the value of $i. The loop runs as long as $j is greater than or equal to 1, and in each iteration, $j is decremented by 1.
  - echo $j; - This prints the value of $j (which is decremented in each iteration) to the output.
2. If $i is odd:
  - for($j=1; $j<=$i; $j++) - This is an inner for loop that initializes a variable $j with the value 1. The loop runs as long as $j is less than or equal to $i, and in each iteration, $j is incremented by 1.
  - echo $j; - This prints the value of $j (which is incremented in each iteration) to the output.
echo "<br>"; - After each inner loop (regardless of whether $i is even or odd), a line break (<br>) is printed to move to the next line.
The outer loop continues to iterate until $i becomes less than 1, at which point the loop exits.
?> - This is the closing tag of the PHP script, indicating the end of PHP code 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.
