Hello internals,It is this time of year again where we proposed a list of deprecations to add in PHP 8.4: https://wiki.php.net/rfc/deprecations_php_8_4 As a reminder, this list has been compiled over the course of the past year by various different people. And as usual, each deprecation will be voted in isolation. We still have a bit of time buffer, so if anyone else has any suggestions, they are free to add them to the RFC. Some should be non-controversial, others a bit more. If such, they might warrant their own dedicated RFC, or be dropped from the proposal altogether.
I would like to propose a deprecation of implicit cast to int of numeric strings using bit shift operators.
For the following reasons:1. In PHP strings are byte arrays and without context it's not possible to know if "123" is actually a number or just three bytes of 0x313234 2. The other bitwise operators `|`, `&`, `~`, `^` already take it as byte array, only the bit shift operators try to be smart here 3. Non numeric strings already fail with "Unsupported operand types: string >> int" 4. This makes working with byte arrays unnecessary hard and forces you to use limited and system depending int's.
https://3v4l.org/IBUDDWhile processing strings as byte arrays using bit shift operators needs a separate RFC, I think, if there is an agreement on deprecating this implicit cast it would already be beneficial to have this sooner than later.
What do you think?
