PHP Number Pattern 54

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

example.php

Copied

<?php
// First Part
for($i=1; $i<=5; $i++)
{
 for($j=1; $j<=5; $j++)
 {
  if($i == $j) 
   echo $j;
  else
   echo "&nbsp;&nbsp;";
 }
 for($k=4; $k>=1; $k--)
 {
  if($i == $k)
   echo $k;
  else
   echo "&nbsp;&nbsp;";
 }
 echo "<br>";
}
// Second Part
for($i=4; $i>=1; $i--)
{
 for($j=1; $j<=5; $j++)
 {
  if($i == $j)
   echo $j;
  else
   echo "&nbsp;&nbsp;";
 }
 for($k=4; $k>=1; $k--)
 {
  if($i == $k)
   echo $k;
  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:

First Part:

This part generates a pattern of numbers increasing from 1 to 5, followed by numbers decreasing from 4 to 1. It creates a diagonal pattern where each row has the row number, followed by spaces, and then the corresponding number from the decreasing sequence.

Here's the breakdown of the first part:
1. The outer loop (for($i=1; $i<=5; $i++)) iterates from 1 to 5, controlling the rows of the pattern.
2. The first nested loop (for($j=1; $j<=5; $j++)) iterates from 1 to 5 for each row, controlling the left half of the pattern.
  - If the value of $i (current row) is equal to $j (current column), it prints the value of $j (the diagonal number).
  - Otherwise, it prints two non-breaking spaces (  ) to create spacing.
3. The second nested loop (for($k=4; $k>=1; $k--)) iterates from 4 to 1 for each row, controlling the right half of the pattern.
  - If the value of $i (current row) is equal to $k (current column in the decreasing sequence), it prints the value of $k (the decreasing diagonal number).
  - Otherwise, it prints two non-breaking spaces for spacing.
4. After each inner loop pair, a line break (<br>) is printed to move to the next row.
Second Part:

This part generates a pattern that is the mirror image of the first pattern. It creates a diagonal pattern where each row has the row number (in decreasing order), followed by spaces, and then the corresponding number from the decreasing sequence (also in decreasing order).

Here's the breakdown of the second part:
1. The outer loop (for($i=4; $i>=1; $i--)) iterates from 4 to 1, controlling the rows of the pattern.
2. The first nested loop (for($j=1; $j<=5; $j++)) iterates from 1 to 5 for each row, controlling the left half of the pattern (similar to the first part).
  - If the value of $i (current row) is equal to $j (current column), it prints the value of $j.
  - Otherwise, it prints two non-breaking spaces for spacing.
3. The second nested loop (for($k=4; $k>=1; $k--)) iterates from 4 to 1 for each row, controlling the right half of the pattern (similar to the first part).
  - If the value of $i (current row) is equal to $k (current column in the decreasing sequence), it prints the value of $k.
  - Otherwise, it prints two non-breaking spaces for spacing.
4. After each inner loop pair, a line break (<br>) is printed to move to the next row.

💯 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.
