PHP Star Pattern 3

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

example.php

Copied

<?php
for($i=1; $i<=5; $i++)
{
 for($j=5; $j>$i; $j--)
  echo "&nbsp;&nbsp;";
 for($k=1; $k<=$i; $k++)
  echo "*";
 echo "<br>";
}
echo "<br>";
?>

💻 Testing the Program

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

Output

    *
   **
  ***

🧠 How the Program Works

Let's break down the logic behind the code:

<?php and ?>: These tags indicate the beginning and end of PHP code blocks.
for($i=1; $i<=5; $i++): This is the outer loop that iterates from 1 to 5. It controls the number of rows in the pattern.
Nested Loop 1 (for($j=5; $j>$i; $j--)): This loop is responsible for printing spaces before the asterisks to create the right-aligned triangle. It iterates from 5 to 1, decreasing by one in each iteration.
- echo "  ": This line prints two non-breaking spaces (HTML entity  ), effectively creating the space between the asterisks and the right edge of the pattern.
Nested Loop 2 (for($k=1; $k<=$i; $k++)): This loop is responsible for printing the asterisks in each row. It iterates from 1 to the current value of $i, which represents the current row number.
- echo "*";: This line prints an asterisk for each iteration of the loop.
echo "<br>";: This line prints a line break (<br>) after each row, creating a new line in the pattern.
The outer loop continues to iterate, and with each iteration, the number of spaces decreases and the number of asterisks increases, creating the right-aligned triangle pattern.
After the outer loop completes, echo "<br>"; is used to create a blank line between the pattern and the rest of the page content.
?>: 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.
