How can you check if a variable is odd in a PHP if statement?

To check if a variable is odd in a PHP if statement, you can use the modulo operator (%) to determine if the variable divided by 2 leaves a remainder of 1. If the remainder is 1, then the variable is odd. Example PHP code snippet: 

$number = 5;

if($number % 2 == 1){
    echo "The number is odd.";
} else {
    echo "The number is even.";
}
