The backtick operator (`dir D:\foo`) is used to execute commands via shell. The same functionality is also available as shell_exec().

This RFC proposes to deprecate it in PHP 7.3 and suggest to use shell_exec() instead, in case PHP decided in future to use backtick enclosed strings for Unicode strings.

None.

7.3

2/3 majority will be required.
