Can I include a file from zip in PHP?

Can I include a file from a zip file in PHP? For example consider I have a zip file - test.zip and test.zip contains a file by the name a.php. Now, what I would like to do is something like below,

include "test.zip/a.php";

Is this possible? If it is can anyone provide me a code snippet?? If not, id there any other alternative to do this??

$zip = new ZipArchive('test.zip');

$tmp = tmpfile();
$metadata = stream_get_meta_data($tmp);

file_put_content($metadata['uri'], $zip->getFromName('a.php'));

include $metadata['uri'];

To go further, you may be interested in PHAR archive, which basically a Zip archive.

Edit:

With a cache strategy:

if (apc_exists('test_zip_a_php')) {
    $content = apc_fetch('test_zip_a_php');
} else {
    $zip = new ZipArchive('test.zip');
    $content = $zip->getFromName('a.php');
    apc_add('test_zip_a_php', $content);
}

$f = fopen('php://memory', 'w+');
fwrite($f, $content);
rewind($f);
// Note to use such include you need  `allow_url_include` directive sets to `On`
include('data://text/plain,'.stream_get_contents($f));

Are you all sure? According to the phar extension, phar is implemented using a stream wrapper, so they can just call

include 'phar:///path/to/myphar.phar/file.php';

But there also exists stream wrappers for zip, see this example, where they call:

$reader->open('zip://' . dirname(__FILE__) . '/test.odt#meta.xml');

To open the file meta.xml in the zip-File test.odt (odt-files are only zip-files with another extension).

Also in another example they directly open a zip file via stream wrapper:

$im = imagecreatefromgif('zip://' . dirname(__FILE__) . '/test_im.zip#pear_item.gif');
imagepng($im, 'a.png');

I have to admit, I do not know how directly it works.

I would try calling

include 'zip:///path/to/myarchive.zip#file.php';

Unlike the phar wrapper the zip wrapper seams to require a sharp, but you can also try it with a slash. But it’s also just an idea from reading the docs.

If it does not work, you can use phars of course.
