Description:
------------
rewind() and fseeking to position zero do not work on Bzip2 file handles. As it works with gz-file pointers, it should work with Bzip2 file pointers as well... This is an issue across all versions of PHP...

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

<?php
$filename = 'some_bz_file.tar.bz2';
$bz = bzopen($filename, "r");
bzread($bz, 10);
rewind($bz);
bzclose($bz);
?>

Warning: rewind(): stream does not support seeking
The error message is quite descriptive.

Perhaps it should support seeking to make it parallel with the other functions?
 [2006-02-15 21:46 UTC] tony2001@php.net 
I'm afraid there is no such possibility at all or do you have a patch?
