PHP Star Pattern 11

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

example.php
Copied
Copy To Clipboard
<?php
for($i=1; $i<=5; $i++)
{
 for($j=$i; $j<=5; $j++)
  echo "*";
 for($k=1; $k<($i*2)-1; $k++)
  echo "&nbsp;&nbsp;";
 for($j=$i; $j<=5; $j++)
  echo "*";
 for($k=1; $k<$i*2; $k++)
  echo "&nbsp;&nbsp;";
 echo "<br>";
}
for($i=4; $i>=1; $i--)
{
 for($j=5; $j>=$i; $j--)
  echo "*";
 for($k=1; $k<($i*2)-1; $k++)
  echo "&nbsp;&nbsp;";
 for($j=5; $j>=$i; $j--)
  echo "*";
 for($k=1; $k<$i*2; $k++)
  echo "&nbsp;&nbsp;";
 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:

  1. <?php - This indicates the start of a PHP script.
  2. for($i=1; $i<=5; $i++) - This initiates the first loop that iterates from 1 to 5 (inclusive) to create the top half of the pattern.
  3. Nested Loop 1 (for($j=$i; $j<=5; $j++)) - This loop prints the asterisks (*) for the left half of the pyramid, starting from the current value of $i and going up to 5.
  4. Nested Loop 2 (for($k=1; $k<($i*2)-1; $k++)) - This loop prints the non-breaking spaces (&nbsp;) between the two halves of the pyramid. The number of spaces is calculated based on the current value of $i.
  5. Nested Loop 3 (for($j=$i; $j<=5; $j++)) - This loop prints the asterisks (*) for the right half of the pyramid, starting from the current value of $i and going up to 5.
  6. Nested Loop 4 (for($k=1; $k<$i*2; $k++)) - This loop prints additional non-breaking spaces (&nbsp;) after the right half of the pyramid.
  7. echo "<br>"; - This prints a line break to move to the next line in the pattern.
  8. After the first loop, the program enters another loop to generate the inverted pyramid pattern:
  9. for($i=4; $i>=1; $i--) - This initiates the second loop that iterates from 4 down to 1 to create the bottom half of the pattern.
  10. Nested Loop 1 (for($j=5; $j>=$i; $j--)) - This loop prints the asterisks (*) for the left half of the inverted pyramid, starting from 5 and going down to the current value of $i.
  11. Nested Loop 2 (for($k=1; $k<($i*2)-1; $k++)) - This loop prints the non-breaking spaces (&nbsp;) between the two halves of the inverted pyramid. The number of spaces is calculated based on the current value of $i.
  12. Nested Loop 3 (for($j=5; $j>=$i; $j--)) - This loop prints the asterisks (*) for the right half of the inverted pyramid, starting from 5 and going down to the current value of $i.
  13. Nested Loop 4 (for($k=1; $k<$i*2; $k++)) - This loop prints additional non-breaking spaces (&nbsp;) after the right half of the inverted pyramid.
  14. echo "<br>"; - This prints a line break to move to the next line in the pattern.
  15. The program ends with ?>, indicating the end of the PHP script.

💯 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.
