PHP Number Pattern 24

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

example.php

Copied

<?php
$k = 1;
for($i=1; $i<=5; $i+=2)
{
 for($j=5; $j>=1; $j--)
 {
  if($j > $i)
   echo " ";
  else
   echo $k++ . " ";
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

    1 
  2 3 4
5 6 7 8 9

🧠 How the Program Works

Let's break down the logic behind the code:

<?php: This is the opening tag for PHP code, indicating the beginning of the PHP script.
$k = 1;: Initializes a variable $k with the value 1. This variable will be used to populate the numbers in the pattern.
for($i=1; $i<=5; $i+=2): This is an outer loop that runs from 1 to 5 with a step of 2. This means it iterates through the values 1, 3, and 5. The loop variable $i is used to control the number of columns in each row.
for($j=5; $j>=1; $j--): This is an inner loop that runs from 5 down to 1. The loop variable $j controls the position of the numbers and spaces in each row.
Inside the inner loop:
- if($j > $i): This condition checks if the value of $j is greater than the value of $i. If true, it prints a non-breaking space to create a visual indentation.
- else: If the above condition is false, it means the current position is where a number should be printed.
  - echo $k++ . " ";: It outputs the value of $k, followed by a space. The post-increment operator $k++ increments the value of $k after it's used.
echo "<br>";: After each inner loop completes, a line break <br> is echoed to move to the next line, creating a new row in the pattern.
The outer loop continues its iterations until the condition $i <= 5 is met.
The program ends with the closing ?> tag, indicating the end of the PHP script.

💯 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.
