How to print even numbers in PHP?

@denis you can use for loop and check with if statement even numbers or not in PHP, code:

1
2
3
4
5
6
7
8

<?php

for ($i = 0; $i <= 20; $i++) {
    if ($i % 2 === 0) {
        echo $i;
    }
}
// Output: 0 2 4 6 8 10 12 14 16 18 20

Another way to print even numbers in PHP is by using a while loop. Here's an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

<?php

$i = 0;

while ($i <= 20) {
    if ($i % 2 === 0) {
        echo $i;
    }
    $i++;
}
// Output: 0 2 4 6 8 10 12 14 16 18 20

In this example, we start with the variable $i set to 0. The while loop will continue running until $i is greater than 20. Inside the loop, we use the modulo operator (%) to check if $i is divisible evenly by 2. If it is, then it is an even number and we echo it. Finally, we increment $i by 1 before the next iteration of the loop.
