PHP Manual


zlib://

bzip2://

zip://

zlib:// -- bzip2:// -- zip://Compression Streams

Description

zlib: PHP 4.0.4 - PHP 4.2.3 (systems with fopencookie only)

compress.zlib:// and compress.bzip2:// PHP 4.3.0 and up

zlib: works like gzopen(), except that the stream can be used with fread() and the other filesystem functions. This is deprecated as of PHP 4.3.0 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.

Options

  • zlib:
  • compress.zlib://
  • compress.bzip2://

Options
