What are best practices to call different methods based on some variable value in PHP? Like this:

if ($var == 'someValue1') {
    $someObj->abc();
} elseif ($var == 'someValue2') {
    $someObj->def();
} elseif ...
} elseif ($var == 'someValueN') {
    $someObj->xyz();
}

It seems that there are many ways to accomplish this task. At least, I've found the following options:

1. Use a bunch of if/else statements


2. Use switch statement


3. Use variable functions


4. Use anonymous function (define an array of anonymous functions)


5. Use call_user_func and call_user_func_array functions


6. Use polymorphism: abstract base class + a bunch of sub-classes (one per actual method)


7. Use eval statement


8. Use ReflectionMethod::invoke method

Maybe, there are some other ways which I haven't found yet.

So, which ways are better and which should be avoided (for situations with 3, 5, 7 and 10+ possible cases)? It is interesting from the following perspectives: speed, readability, maintainability, security, portability (supported by most servers and hosting providers) and understandability for most developers.
