I may have given the impression of stubbornness in this discussion, but I have
listened to people's arguments, and am considering an RFC proposing two
functions:
- a syntactic sugar for array_key_exists and property_exists, maybe called
hasitem(); hasitem($foo['bar']) would check $foo has the item 'bar', but
hasitem($foo) would be an error
- a function for checking if a variable is in the current symbol table, maybe
called variable_exists to match class_exists etc; it would take a string naming
the variable, e.g. variable_exists('foo'); I am worried that this will be
abused, and tempted to give it a "scarier" name
Importantly, neither of these should be presented as "fixing isset", since I
have seen absolutely zero evidence that it is broken; the names and behaviours
are designed to highlight that these are functions to be used for specific
purposes.
