PHP Number Pattern 44

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

example.php

Copied

<?php
// First Part
for($i=1; $i<=5; $i++)
{
 for($j=$i; $j<5; $j++)
  echo "&nbsp;&nbsp;";
 for($k=1; $k<$i*2; $k++)
  echo $k;
 echo "<br>";
}
// Second Part
for($i=4; $i>=1; $i--)
{
 for($j=5; $j>$i; $j--) 
  echo "&nbsp;&nbsp;";
 for($k=1; $k<$i*2; $k++)
  echo $k;
 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:

In the first part, the program is using nested loops to create a pattern of numbers and spaces in a triangle shape, increasing from top to bottom.
1. The outer loop runs from $i = 1 to $i <= 5, controlling the number of rows in the pattern.
2. The first inner loop ($j loop) is responsible for printing the leading spaces before the numbers. It runs from $j = $i to $j < 5, printing two non-breaking spaces (  ) for each iteration to create the indentation.
3. The second inner loop ($k loop) prints the sequence of numbers. It runs from $k = 1 to $k < $i * 2, and it prints the numbers from 1 to ($i * 2 - 1).
4. After each inner loop finishes, a line break (<br>) is printed to move to the next line and start the pattern for the next row.
In the second part, the program generates the second half of the pattern, which is the inverted version of the first part.
1. The outer loop runs from $i = 4 to $i >= 1, controlling the number of rows in the inverted pattern.
2. The first inner loop ($j loop) is responsible for printing the leading spaces before the numbers. It runs from $j = 5 to $j > $i, printing two non-breaking spaces (  ) for each iteration to create the indentation.
3. The second inner loop ($k loop) prints the sequence of numbers. It runs from $k = 1 to $k < $i * 2, and it prints the numbers from 1 to ($i * 2 - 1).
4. After each inner loop finishes, a line break (<br>) is printed to move to the next line and start the pattern for the next row.

💯 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.
