Pattern: Leading backslash in import use
Issue: -
Verifies that a name being imported in an import use statement does not start with a leading backslash.
Names in import use statements should always be fully qualified, so a leading backslash is not needed and it is strongly recommended not to use one.
This sniff handles all types of import use statements supported by PHP, in contrast to other sniffs for the same in, for instance, the PHPCS native PSR12 or the Slevomat standard, which are incomplete.
