PHP Star Pattern 8

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

example.php

Copied

<?php
for($i=5; $i>=1; $i--)
{
 for($j=5; $j>=1; $j--)
 {
  if($i == $j)
   echo "*";
  else
   echo "&nbsp;&nbsp;";
 }
 for($k=2; $k<=5; $k++)
 {
  if($i == $k)
   echo "*";
  else
   echo "&nbsp;&nbsp;";
 }
 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 tag indicates the beginning of PHP code.
for($i=5; $i>=1; $i--): This initializes a loop with the variable $i starting from 5 and decreasing by 1 in each iteration until it reaches 1. This loop controls the number of rows in the pattern.
Inside the outer loop:
1. for($j=5; $j>=1; $j--): This initializes an inner loop with the variable $j starting from 5 and decreasing by 1 in each iteration until it reaches 1. This loop controls the number of columns before the asterisk in each row.
2. Inside the inner loop:
  - if($i == $j): This checks if the current values of $i and $j are equal. If they are equal, an asterisk is printed (echo "*";) to form a diagonal line from the top-left to the bottom-right of the pattern.
  - else: If the values are not equal, two non-breaking space entities are printed (echo "  ";) to create space between the asterisks.
3. for($k=2; $k<=5; $k++): This initializes another loop with the variable $k starting from 2 and increasing by 1 in each iteration until it reaches 5. This loop controls the number of columns after the asterisk in each row.
4. Inside the second inner loop:
  - if($i == $k): This checks if the current values of $i and $k are equal. If they are equal, an asterisk is printed (echo "*";) to form a diagonal line from the bottom-left to the top-right of the pattern.
  - else: If the values are not equal, two non-breaking space entities are printed (echo "  ";) to create space between the asterisks.
5. echo "<br>";: This prints a line break after each row to move to the next line.
The outer loop continues until $i becomes 1, which completes the pattern.
?>: This tag indicates the end of 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.
