How to make the inverted number pyramid using PHP
In this tutorial, we will discuss How to make the inverted number pyramid using PHP. I will let you know the simple process of the inverted number pyramid using PHP with for loop. PHP for loop use execute a block of code for a specified number of times. Using for or for each loop to make an inverted number pyramid is much easier. I am using for loop to inverted number pyramid using PHP because it is easier to understand that how many rows I have to iterate. In this example, we will discuss a 9 to 1 inverted number display. first for loop in $i = 9 ,$i>=1 and $i-- to inverted number.
Example
<?php
for($i=9; $i>=1; $i--) {
echo $i."<br>";
}
Output:
9
8
7
6
5
4
3

Example
<?php
for($i=9; $i>=1; $i--) {
for($k=$i; $k>=1; $k--){
echo " ".$i." ";
}
echo "<br>";
}
Output:
9 9 9 9 9 9 9 9 9
8 8 8 8 8 8 8 8
7 7 7 7 7 7 7
6 6 6 6 6 6
5 5 5 5 5
