PHP Number Pattern 56

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

example.php

Copied

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

💻 Testing the Program

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

Output

        1
      1 2 1 
    1 2 3 2 1
  1 2 3 4 3 2 1
1 2 3 4 5 4 3 2 1

🧠 How the Program Works

Let's break down the logic behind the code:

<?php - This indicates the start of a PHP code block.
for($i=1; $i<=5; $i++) - This is the outer loop that iterates from 1 to 5. The variable $i represents the current iteration.
Inside the outer loop, we have the following:
1. for($j=5; $j>$i; $j--) - This is an inner loop that generates empty <div></div> elements. It starts with $j as 5 and decrements it in each iteration until it's greater than $i.
2. for($k=1; $k<=$i; $k++) - Another inner loop that generates <div> elements with numbers from 1 to the current value of $i.
3. $n = $k - 1; - This line assigns the value of $k - 1 to the variable $n.
4. for($m=1; $m<$i; $m++) - Another inner loop that generates <div> elements with decreasing numbers from $n (pre-decremented in each iteration) down to 1. Note that $n was set to $k - 1 in the previous step.
5. echo "<br>"; - This line outputs an HTML line break <br> after each iteration of the outer loop, creating a new line for the next set of <div> elements.
} - Closes the outer loop.
?> - Indicates the end of the PHP code block.

💯 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.
