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

说明

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.

Example on how to read an entry from a ZIP archive (file "bar.txt" inside "./foo.zip"): <?php $fp = fopen('zip://./foo.zip#bar.txt', 'r'); if( $fp ){ while( !feof($fp) ){ echo fread($fp, 8192); } fclose($fp); } ?> Also, apparently, the "zip:" wrapper does not allow writing as of PHP/5.3.6. You can read http://php.net/ziparchive-getstream for further reference since the underlying code is probably the same.

I had a difficult time finding how to use compress.zlib with an http resource so I thought I would post what I found <?php $file = 'compress.zlib://http://www.example.com/myarchive.gz'; $fr = fopen($file, 'rb'); ?> Per the bugreport I found here (http://bugs.php.net/bug.php?id=29045)
