How to print Left Half Pyramid Pattern in PHP ?

Answer

To print the Left Half Pyramid Pattern in PHP, we use nested loops where the outer loop controls the rows and the inner loop prints spaces and stars.

✐ Examples

1 Left Half Pyramid Pattern

In this example,

We define the size of the pyramid, n, which is set to 5 in this example.
We use two nested loops: an outer loop to handle rows and an inner loop to print spaces and stars.
The outer loop runs from 1 to n, controlling the number of rows.
The inner loop in PHP prints spaces based on the difference between n and the current row, followed by stars equal to the current row number.
This combination of loops and print statements creates the Left Half Pyramid Pattern.

PHP Program

<?php
function printLeftHalfPyramid() {
    $n = 5;
    for ($i = 1; $i <= $n; $i++) {
        $row = '';
        for ($j = 1; $j <= $n - $i; $j++) {
            $row .= ' ';
        }
        for ($k = 1; $k <= $i; $k++) {
            $row .= '*';
        }
        echo $row . "\n";
    }
}

printLeftHalfPyramid();
?>
