How can one check if a $_POST variable is not empty in PHP using an if statement?

To check if a $_POST variable is not empty in PHP, you can use the empty() function within an if statement. If the $_POST variable is not empty, the condition will evaluate to false and any code within the if block will be executed. If the $_POST variable is empty, the condition will evaluate to true and the code within the if block will be skipped. 

if (!empty($_POST['variable_name'])) {
    // Code to execute if $_POST['variable_name'] is not empty
    echo "The variable is not empty!";
} else {
    // Code to execute if $_POST['variable_name'] is empty
    echo "The variable is empty!";
}
