PHP Number Pattern 41

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

example.php

Copied

<?php
$m = 1;
for($i=1; $i<=9; $i+=2)
{
 for($j=$i; $j<9; $j++)
  echo "&nbsp;&nbsp;&nbsp;&nbsp;";
 for($k=1; $k<=$i; $k++)
 {
  echo "<div>". $m*$m ."</div>";
  $m++;
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

                  1
              4   9  16
         25  36  49  64  81
    100 121 144 169 196 225 256
289 324 361 400 441 484 529 576 625

🧠 How the Program Works

Let's break down the logic behind the code:

<?php - This is the opening tag for embedding PHP code in an HTML file.
$m = 1; - Initialize a variable $m with the value 1. This variable will be used to compute the square of numbers.
for($i=1; $i<=9; $i+=2) - Start a loop where the variable $i is initialized to 1, the loop continues as long as $i is less than or equal to 9, and in each iteration, $i is incremented by 2. This loop is used to control the number of rows and the number of elements in each row.
Nested Loop 1 (for($j=$i; $j<9; $j++)) - This loop is used to insert spaces before each group of squares. It starts with the value of $i and continues until $j is less than 9. It prints four non-breaking spaces ( ) to create an indentation for formatting.
Nested Loop 2 (for($k=1; $k<=$i; $k++)) - This loop is used to print the square of numbers. It starts with 1 and continues as long as $k is less than or equal to the value of $i. In each iteration, it prints a <div> element containing the square of $m, which is incremented after each square is printed.
echo "<div>". $m*$m ."</div>"; - This line prints the square of the current value of $m inside a <div> element.
$m++; - Increment the value of $m by 1, preparing it for the next iteration.
echo "<br>"; - Print a line break (<br>) to move to the next row after all squares in the current row have been printed.
The inner two loops and their associated lines of code are nested within the outer loop, creating a pattern where the number of squares printed in each row increases as the value of $i increases.
?> - This is the closing tag for the 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.
