How to print Diamond Pattern in PHP ?

Answer

To print a Diamond Pattern in PHP, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars (*) to form the pattern.

✐ Examples

1 Diamond Pattern

In this example,

We define a function printDiamond that takes the desired number of rows $n as a parameter.
We use two nested for loops, where the outer loop runs from 1 to $n and the inner loops control the spaces and stars in each row.
Within the inner loops, we calculate the number of spaces and stars based on the current row number to form the diamond pattern.

PHP Program

<?php
function printDiamond($n) {
    for ($i = 1; $i <= $n; $i++) {
        $spaces = str_repeat(' ', $n - $i);
        $stars = str_repeat('*', 2 * $i - 1);
        echo $spaces . $stars . "\n";
    }
    for ($i = $n - 1; $i >= 1; $i--) {
        $spaces = str_repeat(' ', $n - $i);
        $stars = str_repeat('*', 2 * $i - 1);
        echo $spaces . $stars . "\n";
    }
}

// Example usage
printDiamond(5);
?>
