PHP Alphabet Pattern 13

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

example.php

Copied

<?php
$alpha = range('A', 'Z');
$k = 0;
for($i=0; $i<=4; $i++)
{
 for($j=0; $j<=$i; $j++)
  echo $alpha[$k++] . "&nbsp;";
 echo "<br>";
}
?>

💻 Testing the Program

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

Output

A
B C
D E F
G H I J
K L M N O

🧠 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 file.
$alpha = range('A', 'Z');: This line creates an array called $alpha containing all capital letters from 'A' to 'Z'. This array will be used to print the letters in the pattern.
$k = 0;: Initializes a variable $k with the value 0. This variable will be used to keep track of the index of the current alphabet in the $alpha array.
for($i=0; $i<=4; $i++): This is an outer loop that iterates 5 times, starting from 0 and going up to 4. This controls the number of rows in the pattern.
Inside the outer loop:
- for($j=0; $j<=$i; $j++): This is an inner loop that iterates from 0 up to the current value of $i. This controls the number of columns (alphabets) in each row.
- echo $alpha[$k++] . " ";: This line prints the current alphabet from the $alpha array using the index $k, and then increments $k to point to the next alphabet. The   is an HTML entity for a non-breaking space, used to add space between alphabets.
- echo "<br>";: This line prints an HTML line break element, moving the output to the next line after each 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.

✔ Conclusion:

Creating visually appealing patterns is not only a fun endeavour but also a great way to enhance your programming or design skills. We hope this tutorial has inspired you to explore the world of creative coding. Share your creations with us, and let your imagination run wild!

Once the inner loop finishes execution for each row, the outer loop proceeds to the next row, and the pattern continues to be printed.
After the loops complete execution, the PHP code ends with ?>.
