PHP Number Pattern 46

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

example.php

Copied

<?php
$k = 5;
for($i=$k; $i>=1; $i--)
{
 for($j=$k; $j>=1; $j--)
 {
  if($j > $i)
   echo $j . " ";
  else
   echo $i . " ";
 }
 for($j=2; $j<=$k; $j++)
 {
  if($j > $i)
   echo $j . " ";
  else
   echo $i . " ";
 }
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

5 5 5 5 5 5 5 5 5
5 4 4 4 4 4 4 4 5
5 4 3 3 3 3 3 4 5
5 4 3 2 2 2 3 4 5
5 4 3 2 1 2 3 4 5

🧠 How the Program Works

Let's break down the logic behind the code:

$k = 5;: Initializes the variable $k with the value 5.
for($i=$k; $i>=1; $i--): This outer loop iterates from the value of $k (5 in this case) down to 1 in each iteration. It controls the rows of the pattern.
Inside the outer loop, there are two nested loops:
1. for($j=$k; $j>=1; $j--): This inner loop iterates from the value of $k down to 1 in each iteration. It controls the columns of the left half of each row.
2. if($j > $i) echo $j . " "; else echo $i . " ";: Depending on the relationship between $j and $i, this conditional statement prints either $j or $i, followed by a space. If $j is greater than $i, it prints the value of $j, otherwise, it prints the value of $i.
After the first inner loop, there is a second inner loop:
1. for($j=2; $j<=$k; $j++): This loop iterates from 2 to the value of $k (5 in this case). It controls the columns of the right half of each row.
2. if($j > $i) echo $j . " "; else echo $i . " ";: Similar to the previous conditional statement, this prints either $j or $i based on the relationship between $j and $i.
echo "<br>";: After each row, a line break (<br>) is printed to move to the next line.

💯 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.
