PHP Number Pattern 15

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=$i; $j>=1; $j--)
  echo $j % 2;
 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:

<?php and ?>: These tags indicate the start and end of PHP code within an HTML document.
for($i=1; $i<=5; $i++): This is the outer loop that iterates through values of $i from 1 to 5, incrementing by 1 in each iteration.
{: The opening curly brace signifies the start of the code block associated with the outer loop.
for($j=$i; $j>=1; $j--): This is the inner loop that iterates through values of $j from the current value of $i down to 1, decrementing by 1 in each iteration. This inner loop is used to print the numbers on each line of the pattern.
echo $j % 2;: The echo statement prints the value of $j % 2 on the same line. Here, $j % 2 calculates the remainder when $j is divided by 2. Since we are printing the result of the modulo operation, the output will be either 0 or 1, representing even or odd numbers respectively.
echo "<br>";: After the inner loop finishes printing numbers for a particular line, this statement adds a line break (<br>) to move to the next line in the output.
}: The closing curly brace marks the end of the code block associated with the inner loop.
echo "<br>";: After the outer loop finishes iterating, this statement adds an additional line break to separate the pattern from any content that might come after it.
}: The closing curly brace marks the end of the code block associated with the outer loop.

💯 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.
