PHP Number Pattern 31

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=1; $j<$i*2; $j++)
 {
  if($j%2 == 0)
   echo "*";
  else
   echo $i;
 }
 echo "<br>";
}
// Second Part
for($i=4; $i>=1; $i--)
{
 for($j=1; $j<$i*2; $j++)
 {
  if($j%2 == 0)
   echo "*";
  else
   echo $i;
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

1
2*2
3*3*3
4*4*4*4
5*5*5*5*5
4*4*4*4
3*3*3
2*2
1

🧠 How the Program Works

Let's break down the logic behind the code:

First Part:
1. The outer for loop runs from $i = 1 to $i <= 5.
2. The inner for loop runs from $j = 1 to $j < $i * 2.
3. Within the inner loop, the code checks if $j is even using the condition $j % 2 == 0. If it's even, it prints an asterisk *, otherwise, it prints the value of $i.
4. After the inner loop completes, a line break <br> is printed to move to the next line.
Second Part:
1. The outer for loop runs from $i = 4 to $i >= 1.
2. The inner for loop runs from $j = 1 to $j < $i * 2.
3. Similar to the first part, within the inner loop, the code checks if $j is even using the condition $j % 2 == 0. If it's even, it prints an asterisk *, otherwise, it prints the value of $i.
4. After the inner loop completes, a line break <br> is printed to move to the next line.

💯 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.
