PHP Star Pattern 7

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=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:

  1. Opening PHP Tags: The program starts with the PHP opening tag <?php.
  2. Outer Loop ($i Loop): The outer loop runs from 1 to 5 (both inclusive), with the loop variable $i starting at 1. This loop controls the overall structure of the pattern.
    • for($i=1; $i<=5; $i++): This loop initializes $i to 1, and as long as $i is less than or equal to 5, it runs the loop body and increments $i by 1 in each iteration.
  3. First Inner Loop ($j Loop): Inside the outer loop, there's another loop that runs from 5 to 1 (both inclusive), controlled by the loop variable $j. This loop is responsible for printing the asterisk (*) character when $i is equal to $j.
    • for($j=5; $j>=1; $j--): This loop initializes $j to 5, and as long as $j is greater than or equal to 1, it runs the loop body and decrements $j by 1 in each iteration.
  4. Asterisk or Space Printing (if-else Block for $j Loop): Inside the $j loop, there's an if-else block that checks if the value of $i is equal to the value of $j.
    • if($i == $j): If $i is equal to $j, it means that the current position in the pattern should have an asterisk (*) printed.
    • else: If $i is not equal to $j, it means that the current position should have two non-breaking spaces (&nbsp;&nbsp;) printed.
  5. Second Inner Loop ($k Loop): After the $j loop, there's another loop that runs from 2 to 5 (both inclusive), controlled by the loop variable $k. This loop is responsible for printing the asterisk (*) character when $i is equal to $k.
    • for($k=2; $k<=5; $k++): This loop initializes $k to 2, and as long as $k is less than or equal to 5, it runs the loop body and increments $k by 1 in each iteration.
  6. Asterisk or Space Printing (if-else Block for $k Loop): Inside the $k loop, there's an if-else block that checks if the value of $i is equal to the value of $k.
    • if($i == $k): If $i is equal to $k, it means that the current position in the pattern should have an asterisk (*) printed.
    • else: If $i is not equal to $k, it means that the current position should have two non-breaking spaces (&nbsp;&nbsp;) printed.
  7. Line Break (<br>): After the inner loops are executed for a particular value of $i, a line break (<br>) is printed to move to the next line before the next iteration of the outer loop starts.
  8. Closing PHP Tags: The program ends with the PHP closing tag ?>.

💯 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.
