超越PHP - Exceed PHP: bzopen

Description

resource bzopen ( string filename, string mode)

bzopen() opens a bzip2 (.bz2) file for reading or writing. filename is the name of the file to open. mode is similar to the fopen() function (`r' for read, `w' for write, etc.).

If the open fails, bzopen() returns FALSE, otherwise it returns a pointer to the newly opened file.

例子 1. bzopen() example

<?php $file = "/tmp/foo.bz2"; $bz = bzopen($file, "r") or die("Couldn't open $file for reading"); bzclose($bz); ?>

See also bzclose().

Note that the provided example seems to contradict the manual entry for
bzread().  

The number of bytes read is the number of uncompressed
bytes, according to bzread().  Since the filesize is likely to be much
smaller than the actual uncompressed size the provided example will not
print out the total contents of the file.
