Variable Variables
- tbm57 3y agothis looks like this is specific to PHP? does this imply the existence of variable variable variables?
- bell-cot 3y agoThis feature is just a limited sort of pointers. You can do similar stuff in ~40-year-old sh shell code - with tricks like `eval echo \$$foo` - so I'd bet that the concept is older (& more common) than dirt.
