<simpara>
|
|
<filename>zlib:</filename> works like <function>gzopen</function>, except that the
|
|
stream can be used with <function>fread</function> and the other
|
|
filesystem functions. This is deprecated as of PHP 4.3.0 due
|
|
to ambiguities with filenames containing ':' characters; use
|
|
<filename>compress.zlib://</filename> instead.

</simpara>
|

|
|
<simpara>
|
|
<filename>compress.zlib://</filename> and
|
|
<filename>compress.bzip2://</filename> are equivalent to
|
|
<function>gzopen</function> and <function>bzopen</function>
|
|
respectively, and operate even on systems that do not support
|
|
fopencookie.
