The zend_string conversion in bcb05dc replaced the length check with zend_string_starts_with(), which also matches on equality. A path equal to remove_path then hits the non-slash branch, strips its whole length and produces an empty archive entry name instead of keeping the path. Closes phpGH-22973

zend_string_starts_with()also matches on equality, so the length check dropped in bcb05dc was load-bearing. A globbed path that equals remove_path now reads its own NUL terminator in theIS_SLASHtest, falls into the non-slash branch and strips its whole length, so the entry lands in the archive under an empty name. Before the conversion the path was kept as-is, which is what 8.4 and 8.5 still do.
