Hi,

As the functions do not always *add* a prefix, I'd suggest to consider 
names like `ensure_prefix` or `enforce_prefix` instead.

Something like `ensure_str_starts_with` or `ensure_starts_with` would be 
a nicer fit with the `str_starts_with`, but then it doesn't rhyme with 
the other prefix/suffix functions that well.

Otherwise I can only say that I've had to solve the same tasks in 
multiple projects, so I'd enjoy such functions being available in PHP 
itself.

BR,
Juris
