PHP Number Pattern 55

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

example.php

Copied

<?php
for($i=1; $i<=5; $i++)
{
 $k = 4;
 $res = $i;
 for($j=$i; $j<$i+$i; $j++)
 {
  if($i == $j)
   echo "<div>". $j. "</div>"; 
  else 
  {
   $res = $res + $k;
   echo "<div>". $res. "</div>";
   $k--;
  }
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

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

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with opening a PHP tag <?php.
The outermost loop uses the variable $i to iterate from 1 to 5. The loop structure is for($i=1; $i<=5; $i++).
Inside the outer loop, two variables $k and $res are initialized. $k is set to 4, and $res is set to the current value of $i.
The inner loop uses the variable $j to iterate from $i to $i + $i - 1. This loop is designed to create a pattern of values that will be echoed.
Inside the inner loop, there is an if condition that compares $i and $j. If they are equal, a <div> element is echoed with the value of $j inside it.
If the if condition is not met (meaning $i is not equal to $j), the program enters the else block. In the else block:
- The value of $res is updated by adding the value of $k to it. This is done to generate a sequence of values based on the previous value of $res.
- The updated value of $res is echoed inside a <div> element.
- The value of $k is decremented by 1.
After the inner loop completes, a <br> element is echoed to start a new line in the HTML output.
The outer loop continues its iterations until $i reaches 5.
Once the outer loop completes, the PHP program ends with a closing tag ?>.

💯 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.
