PHP Number Pattern 18

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

example.php

Copied

<?php
for($i=1; $i<=5; $i++)
{
 if($i%2 == 0)
  $k = 2;
 else
  $k = 1;
 for($j=1; $j<=$i; $j++)
 {
  echo $k . " "; 
  $k += 2; 
 }
 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:

The outer for loop: for($i=1; $i<=5; $i++)
- This loop runs five times, with $i taking values from 1 to 5. It controls the number of rows in the pattern.
Inside the outer loop, an if statement:
- if($i%2 == 0): Checks if the current value of $i is even.
- If $i is even, it sets $k to 2; otherwise, it sets $k to 1.
Inner for loop: for($j=1; $j<=$i; $j++)
- This loop runs from 1 to the current value of $i. It controls the number of columns in each row.
Inside the inner loop:
- echo $k . " ";: Outputs the value of $k followed by a space.
- $k += 2;: Increments the value of $k by 2. This prepares the next value to be printed in the next iteration of the inner loop.
echo "<br>";: Outputs an HTML line break (<br>) after each row is printed. This moves the output to the next line for the next row.

💯 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.
