Can someone explain to me to the logic behind the %2. Although I do know the variable $i is changing every time it loops. I'd like to know what the %2 means.

PHP Code:

$i=0;
while($i < 10){
    
    if($i%2){
        $color = 'class="blue"';
    }
    else{
    $color = 'class="red"';    
    }
    echo '<h2 '.$color.'>Text</h2>';
    
    $i++;
} 


% is the modulus operator. It gives the remainder of an integer division of the operands.

In this case, $i % 2 will be 1 if $i is even, and 0 if it is odd.

Thanks appreciate it.
