PHP Number Pattern 29

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

example.php

Copied

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

Opening PHP Tag: <?php indicates the start of a PHP code block.
Outer Loop: The first for loop initializes a variable $i to 1, runs as long as $i is less than or equal to 5, and increments $i by 1 in each iteration. This loop controls the number of rows in the pattern.
Inner Loop 1: Inside the outer loop, there's another for loop that initializes a variable $j to 1, runs as long as $j is less than or equal to 5, and increments $j by 1 in each iteration. This loop controls the printing of numbers up to $i in each row.
- If-Else Condition 1: Inside the inner loop, there's an if-else condition that checks if $j is less than or equal to $i. If the condition is true, it prints the value of $j. Otherwise, it prints three non-breaking space entities(&nbsp) to create spacing.
Inner Loop 2: After the inner loop 1, there's another for loop that initializes a variable $k to 5, runs as long as $k is greater than or equal to 1, and decrements $k by 1 in each iteration. This loop controls the printing of numbers from 5 down to $i in each row.
- If-Else Condition 2: Inside this loop, there's another if-else condition that checks if $k is greater than $i. If true, it prints a space character. Otherwise, it prints the value of $k.
Line Break: After both inner loops complete, the program prints a <br> tag to move to the next line (row) of the pattern.
Closing Braces: The closing braces (}) denote the end of the inner and outer loops.
Closing PHP Tag: ?> indicates the end of the PHP code block.

💯 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.
