PHP Number Pattern 57

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=5; $j>=1; $j--)
 {
  if($i == $j)
   echo $j;
  else
   echo "&nbsp;&nbsp;";
 }
 for($k=2; $k<=5; $k++)
 {
  if($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:

for($i=1; $i<=5; $i++): This initializes a loop that runs from 1 to 5, with the variable $i representing the current iteration.
Inside the first loop, there are two nested loops:
1. for($j=5; $j>=1; $j--): This initializes a loop that runs from 5 to 1 in reverse order, with the variable $j representing the current iteration. This loop is responsible for printing numbers in a decreasing order.
2. Inside the $j loop, there's an if-else block:
  - if($i == $j): If the value of $i is equal to the value of $j, it means that the current row number ($i) matches the current column number ($j). In this case, the program echoes the value of $j, which is a number between 1 and 5.
  - else: If the values are not equal, the program echoes   , which represents two non-breaking space entities. This is used to create space between the numbers.
After the first nested loop (loop $j), there's another nested loop:
1. for($k=2; $k<=5; $k++): This initializes a loop that runs from 2 to 5, with the variable $k representing the current iteration. This loop is responsible for printing numbers in an increasing order, except for the first iteration.
2. Inside the $k loop, there's an if-else block:
  - if($i == $k): If the value of $i is equal to the value of $k, it means that the current row number ($i) matches the current column number ($k). In this case, the program echoes the value of $k, which is a number between 2 and 5.
  - else: If the values are not equal, the program echoes    to create space.
echo "<br>";: After each iteration of the outermost loop ($i), this line is executed to print a line break, moving to the next row in the pattern.

💯 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.
