PHP Number Pattern 23

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

example.php

Copied

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

💻 Testing the Program

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

Output

1234554321
1234**4321
123****321
12******21
1********1

🧠 How the Program Works

Let's break down the logic behind the code:

<?php: This is the opening tag that indicates the start of PHP code.
for($i=5; $i>=1; $i--): This is the outer loop that iterates over values of $i from 5 down to 1, decrementing by 1 in each iteration.
{: Opening curly brace to mark the beginning of the outer loop's block.
for($j=1; $j<=$i; $j++): This is the first nested loop. It initializes $j to 1 and then increments $j in each iteration until it's less than or equal to the current value of $i.
echo $j;: This statement outputs the value of $j (which is the current number within the range) on the same line.
for($k=$i; $k<5; $k++): This is the second nested loop. It initializes $k with the value of $i and then increments $k until it's less than 5.
echo "**";: This statement outputs two asterisks '**' on the same line. The number of asterisks is determined by the difference between 5 and the current value of $i.
for($m=$i; $m>=1; $m--): This is the third nested loop. It initializes $m with the current value of $i and then decrements $m until it's greater than or equal to 1.
echo $m;: This statement outputs the value of $m (which is the current number within the range) on the same line.
echo "<br>";: This statement adds a line break (<br>) to move to the next line in the output.
}: Closing curly brace to mark the end of the outer loop's block.
?>: This is the closing tag that indicates the end of PHP code.

💯 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.
