Function return error/sucess

Hi,
This is an extremely simplified version of my code:

function action($id)
{
     if($id == 6)
    {
          // Sucess
    }
    else
    {
         // Error
    }
}

$id = 6

if(action($id) is error)
{
     // Do something
}
else
{
     // Do something
}

PHP:

could someone complete that code for me. I hoppe it makes sence (If not please say )

 

function action($id)
{
     if($id == 6)
    {
          return true;
    }
    else
    {
         return false;
    }
}

$id = 6;

if(action($id))
{
     echo 'Success';
}
else
{
     echo 'Failure';
}

PHP:

The above will echo Success if your ID is 6 or Failure if the id is not 6.

 

ahh thank you thats perfect.

 

Better still just use

function action($id) {
    return ($id == 6);
}

PHP:

for the function instead
