You can use PHP's <a href="http://php.net/manual/en/book.zip.php" rel="noreferrer">Zip</a> class to create zip files, and <a href="http://php.net/manual/en/book.zlib.php" rel="noreferrer">ZLib</a> to create gzip files.

Creating a <code>.zip</code> file:

<pre><code>$zip = new ZipArchive();
$res = $zip-&gt;open('test.zip', ZipArchive::CREATE);
$zip-&gt;addFromString('test.txt', 'file content goes here');
$zip-&gt;addFile('data.txt', 'entryname.txt');
$zip-&gt;close();
</code></pre>

Creating a <code>.gz</code> file:

<pre><code>$file = "test.txt";
$gzfile = "test.gz";
$fp = gzopen($gzfile, 'w9'); // w == write, 9 == highest compression
gzwrite($fp, file_get_contents($file));
gzclose($fp);

Pay attention to the notes section on how to protect from malicious input.

You can also use <a href="https://www.php.net/manual/en/wrappers.compression.php" rel="nofollow noreferrer">PHP compression stream wrappers</a> to compress and uncompress files in one line:

<pre class="lang-php prettyprint-override"><code>// Reads file.txt, passes it throyuh the zlib wrapper and writes the archive file.txt.gz
copy('data.xls', 'compress.zlib://' . 'data.xls.gz');

// Reads the archive file.txt.gz using zlib wrapper, writes uncompressed file
copy('compress.zlib://' . 'data.xls.gz', 'data.xls');
