PHP Number Pattern 28

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

example.php

Copied

<?php
for($i=10; $i>=1; $i--)
{
 for($j=$i; $j<10; $j++)
  echo $j;
 echo "0";
 for($k=9; $k>=$i; $k--)
  echo $k;
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

0
909
89098
7890987
678909876
56789098765
4567890987654
345678909876543
23456789098765432
1234567890987654321

🧠 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=10; $i>=1; $i--): This is the outer loop that initializes a variable $i to 10 and iterates as long as $i is greater than or equal to 1. In each iteration, $i is decremented by 1.
{: Opening brace to define the start of the outer loop's block.
for($j=$i; $j<10; $j++): This is the first inner loop. It initializes a variable $j to the value of $i and iterates as long as $j is less than 10. In each iteration, $j is incremented by 1.
echo $j;: This statement prints the value of $j (which starts from $i) in the current iteration of the inner loop.
echo "0";: This statement prints the digit "0" after the inner loop has completed.
for($k=9; $k>=$i; $k--): This is the second inner loop. It initializes a variable $k to 9 and iterates as long as $k is greater than or equal to the value of $i. In each iteration, $k is decremented by 1.
echo $k;: This statement prints the value of $k in the current iteration of the second inner loop.
echo "<br>";: This statement prints an HTML line break tag "<br>" to create a new line after each iteration of the outer loop.
}: Closing brace to define the end of the outer loop's block.
}: Closing brace to define 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.
