How can I unzip a .gz file with PHP?

Question

I\'m using CodeIgniter and I can\'t figure out how to unzip files!

Answer 1

Use the functions implemented by the Zlib Compression extension.

This snippet shows how to use some of the functions made available from the extension:

// open file for reading
$zp = gzopen($filename, "r");

// read 3 char
echo gzread($zp, 3);

// output until end of the file and close it.
gzpassthru($zp);
gzclose($zp);
