PHP Number Pattern 51

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

example.php

Copied

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

💻 Testing the Program

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

Output

1
3 2
4 5 6
10 9 8 7
11 12 13 14 15

🧠 How the Program Works

Let's break down the logic behind the code:

Initialize two variables $k and $m both to 1. These will be used to keep track of values as the loops progress.
Start a for loop with the counter variable $i initialized to 1. The loop will continue as long as $i is less than or equal to 5.
Inside the outer loop, set the value of $m to $k + $i - 1. This means that $m will have a value equal to the current value of $k plus the current value of $i minus 1. This calculation will be updated in each iteration of the outer loop.
Start an inner for loop with the counter variable $j initialized to 1. The loop will continue as long as $j is less than or equal to the current value of $i.
Inside the inner loop, there is an if condition to check whether the value of $i is odd (i.e., $i % 2 == 1). If this condition is true, it means the current row number is odd.
If the row number is odd, the program prints a <div> element containing the value of $k.
If the row number is even, the program prints a <div> element containing the value of $m, and then decrements the value of $m by 1.
After printing the appropriate <div> element, the program increments the value of $k by 1.
After the inner loop completes, the program prints a <br> element to move to the next line.
Repeat the outer loop with the next value of $i, until $i reaches 5.

💯 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.
