zlib:// -- bzip2:// -- zip:// — 压缩流
zlib: PHP 4.0.4 - PHP 4.2.3(仅支持带 fopencookie 的系统)
compress.zlib:// 和 compress.bzip2:// PHP 4.3.0 及以上
zlib: 的功能类似 gzopen(),但是 其数据流还能被 fread() 和其他文件系统函数使用。 自 PHP 4.3.0 后这个不建议被使用,因为会和其他带“:”字符的文件名混淆; 请使用 compress.zlib:// 作为替代。
compress.zlib://、 compress.bzip2:// 和 gzopen()、 bzopen() 是相等的。并且可以在不支持 fopencookie 的系统中使用。
ZIP 扩展 注册了 zip: 封装协议。

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)
