zlib:// -- bzip2:// -- zip:// — Compression Streams
Description
compress.zlib:// and compress.bzip2://
zlib: works like gzopen(), except that the
stream can be used with fread() and the other
filesystem functions. This is deprecated due
to ambiguities with filenames containing ':' characters; use
compress.zlib:// instead.
compress.zlib:// and
compress.bzip2:// are equivalent to
gzopen() and bzopen()
respectively, and operate even on systems that do not support
fopencookie.
ZIP extension registers zip: wrapper. As of
PHP 7.2.0 and libzip 1.2.0+, support for the passwords for encrypted archives were added, allowing
passwords to be supplied by stream contexts. Passwords can be set using the 'password'
stream context option.
