PHP Alphabet Pattern 19

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

example.php

Copied

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

💻 Testing the Program

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

Output

A        A
AB      BA  
ABC    CBA
ABCD  DCBA
ABCDEEDCBA

🧠 How the Program Works

Let's break down the logic behind the code:

$alpha = range('A', 'Z');: This line creates an array $alpha containing the uppercase letters of the English alphabet from 'A' to 'Z'.
for($i=0; $i<=4; $i++): This is the outer loop that iterates 5 times, from 0 to 4. It controls the rows of the pattern.
for($j=0; $j<=4; $j++): This is the inner loop that also iterates 5 times, from 0 to 4. It controls the columns of the pattern for the first half of each row.
if($j<=$i) echo $alpha[$j]; else echo "  ";: Inside the inner loop, this condition checks if the column index $j is less than or equal to the row index $i. If true, it prints the letter at index $j from the $alpha array. Otherwise, it prints two non-breaking space HTML entities to create spacing.
for($k=4; $k>=0; $k--): This is another inner loop that iterates 5 times in reverse order, from 4 to 0. It controls the columns of the pattern for the second half of each row.
if($k > $i) echo "   "; else echo $alpha[$k];: Inside the second inner loop, this condition checks if the column index $k is greater than the row index $i. If true, it prints two non-breaking space HTML entities for spacing. Otherwise, it prints the letter at index $k from the $alpha array.
echo "<br>";: After each row is constructed by the inner loops, this line prints a line break (<br>) to move to the next line in the output.
The loops continue iterating according to their respective conditions, constructing the desired 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.
