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

Descrição

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)
