gzopen ( string filename, string mode [, int use_include_path])
Opens a gzip (.gz) file for reading or writing. The mode
parameter is as in fopen() ("rb" or "wb") but
can also include a compression level ("wb9") or a strategy: 'f'
for filtered data as in "wb6f", 'h' for Huffman only compression
as in "wb1h". (See the description of deflateInit2 in zlib.h for
more information about the strategy parameter.)
gzopen() can be used to read a file which is
not in gzip format; in this case gzread() will
directly read from the file without decompression.
gzopen() returns a file pointer to the file
opened, after that, everything you read from this file descriptor
will be transparently decompressed and what you write gets
compressed.
If the open fails, the function returns FALSE.
You can use the optional third parameter and set it to "1", if
you want to search for the file in the include_path, too.
Example 1. gzopen() Example
<?php
$fp = gzopen("/tmp/file.gz", "r");
?>
