gzpassthru

(PHP 3, PHP 4, PHP 5)

Reads to EOF on the given gz-file pointer from the current position and
writes the (uncompressed) results to standard output.

Note:
You may need to call gzrewind() to reset the file
pointer to the beginning of the file if you have already written data
to it.

Tip:
If you just want to dump the contents of a file to the output buffer,
without first modifying it or seeking to a particular offset, you may
want to use the readgzfile() function, which saves
you the gzopen() call.

The gz-file pointer. It must be valid, and must point to a file
successfully opened by gzopen().

The number of uncompressed characters read from gz
and passed through to the input, or FALSE on error.

Example 1. gzpassthru() example

$fp = gzopen('file.gz', 'r');
gzpassthru($fp);
gzclose($fp);
