PHP Number Pattern 21

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

example.php

Copied

<?php
for($i=1; $i<=5; $i++)
{
 echo $i . " ";
 $m = 4;
 $k = $i + $m;
 for($j=1; $j<$i; $j++)
 {
  echo $k . " ";
  $m--;
  $k = $k + $m;
 }
 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 outer loop:
- The outer for loop initializes a variable $i with the value 1.
- It checks whether $i is less than or equal to 5.
- If the condition is true, the loop body is executed, otherwise, the loop terminates.
Inside the outer loop:
- echo $i . " ";: This prints the value of $i followed by a space.
- $m = 4;: Initializes a variable $m with the value 4.
- $k = $i + $m;: Calculates the value of $k by adding $i and $m.
The inner loop:
- Inside the inner loop, another variable $j is initialized with the value 1.
- The loop runs while $j is less than $i.
Inside the inner loop:
- echo $k . " ";: This prints the value of $k followed by a space.
- $m--;: Decrements the value of $m by 1.
- $k = $k + $m;: Calculates the new value of $k by adding $k and $m.
After the inner loop:
- echo "<br>";: This prints an HTML line break, causing the output to move to the next line.
The outer loop increments:
- After the inner loop is completed, the outer loop increments the value of $i by 1.
- The process continues until $i reaches 5.
Final output:
- The program generates a pattern of numbers and spaces in each line, where each line has an increasing sequence of numbers.
- The first number in each line starts from 1 and increases by 1.
- The subsequent numbers are calculated based on the previous value of $k and the decrementing value of $m.

💯 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.
