Question

How would you make a if statement that echo’s if a variable has a value in it and if it has no value in it, it does not echo anything.I know you would use else if there wasn’t a value and I know how to make if statements but I don’t know how I would use one to determine if a value is present or not.
Like

if($additional == ' '){}
else{echo 'Additional information:', $additional;}

Answer 1

if(!empty($variable)){
      echo $varibale     // if the condition check its not empty it will output it
}
else{
     // do nothing      - while when your variable has no value it will do nothing in else
}

But even if you don`t put else nothing will be output since your condition state that you should echoed that variable if it has a value …….
