PHP Number Pattern 17

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

example.php

Copied

<?php
for($i=1; $i<=10; $i+=2)
{
 for($j=$i; $j<=10; $j+=2)
  echo $j;
 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:

<?php: This is the opening tag of PHP, indicating the beginning of a PHP script.
for($i=1; $i<=10; $i+=2): This is the outer loop. It initializes a variable $i to 1 and runs the loop as long as $i is less than or equal to 10. In each iteration, $i is incremented by 2. This means the loop will run with values of $i as 1, 3, 5, 7, and 9.
Inside the outer loop, we encounter the inner loop:
- for($j=$i; $j<=10; $j+=2): This is the inner loop. It initializes a variable $j to the current value of $i (1 in the first iteration) and runs as long as $j is less than or equal to 10. In each iteration, $j is incremented by 2. This means the inner loop will run with values of $j as 1, 3, 5, 7, and 9 in the first iteration, and then continue with the same pattern for subsequent iterations.
Inside the inner loop, we have:
- echo $j;: This statement outputs the current value of $j.
After the inner loop, we have:
- echo "<br>";: This statement outputs an HTML line break (<br>) to create a new line in the HTML output. This will separate each set of numbers printed by the inner loop on different lines.
The nested loops continue executing based on the conditions mentioned until the outer loop completes its iterations.
Once the outer loop finishes, the PHP script ends.

💯 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.
