I just thought of two reasons to use a function call instead of just
a variable assignment.
1. You could pass the entire string into the function call. If
the function doesn't have a variable of that name, it just returns
the string that is passed in:
show_string('Do you really mean it')
function show_string($key) {
If ( ! ($lang[$key] ) {
return $key;
}
This would make it easy when developing code to get everything right
before creating abbreviation keys and changes to the translation file
or database.
The other reason is so that the function can log certain types of
messages that are very unexpected, (Database not available or 'Cant
write to file XYZ fior instance) or indicate a possible security
breach or hacking attempt ( "Too many login attempts" )
