Create Inverted Left Angle Triangle Pattern in PHP Using For Loop

This PHP script uses nested `for` loops to print a inverted left-angle triangle pattern made up of asterisk (`*`) characters.

- The outer `for` loop runs 5 times, starting from 1 and incrementing up to 5. Each iteration of this loop represents a line in the pattern.

- The first inner `for` loop prints spaces. It runs as many times as the current line number, so the number of spaces increases as you go down the lines.

- The second inner `for` loop prints the asterisks. It starts from 5 and decrements down to the current line number, so the number of asterisks decreases as you go down the lines, creating the shape of the inverted left-angle triangle.

- After the asterisks and spaces are printed for a line, a line break (`<br/>`) is printed to move to the next line.

The size of the inverted left-angle triangle (i.e., the number of lines) can be adjusted by changing the initial and final values in the outer `for` loop. This script is a simple demonstration of how nested loops can be used to create patterns in PHP. It's a great exercise for those learning PHP and wanting to improve their understanding of loops.

<?php

for ($a = 1;$a <= 5;$a++)
{
    for ($b = 1;$b <= $a;$b++)
    {
        echo "&nbsp ";
    }
    for ($c = 5;$c >= $a;$c--)
    {
        echo " * ";
    }
    echo "<br/>";
}

?>

Output :
