Question

I am using Codeignitor for programming and coming from c#.
its look like a newbie question ,but i want to do something like this.

I have some functions that which return some values :

Example :

function Create_db()
{

//do something

      if (PassWordError) //some errors here it is password incorrect
       {
         return "PASS_ERROR";
       }

}

and in some places i am using like this

$result = Create_db(); //assume that there are some problems and returned "PASS_ERROR"

so that the $result is string now,

is there anything like ENUMS in php ? or something like that ?

so that i can do something like this :

if (passWordError)
{
  return $error->PasswordError();
}

i assume that i can have some others types too

like

Maximum_name_error,authenticationFailedError etc

Thank you.

A typical approach to doing this in PHP would be to use class constants:

class Something {
    const ERR_HI = 'hi';
    const ERR_FOOBAR = 'foobar';
}


//to use:
return Something::ERR_FOOBAR;

Although I would consider using exceptions instead.
