Hereby, interned strings are supported in thread safe PHP. The patch implements two types of interned strings - interning per process, strings are not freed till process end - interning per request, strings are freed at request end There is no runtime interning. With Opcache, all the permanent iterned strings are copied into SHM on startup, additional copying into SHM might happen on demand.
