All of the existing solutions I found +all generate a local temp file, which means the server needs to </p> + +<ul> +<li>have a web-writable directory large enough to store the +intermediate temp file, and</li> +<li>be able to generate and start streaming the entire file before +the client times out </li> +</ul> + +<p>I wasn't particularly fond of either constraint, so I came up with a +solution: <a href="http://pablotron.org/software/zipstream-php/" title="ZipStream-PHP project page.">ZipStream-PHP</a>. ZipStream is a library for dynamically +streaming dynamic zip files from PHP without writing to the disk at all +on the server. Using it is dirt simple, too. Here's how:</p> + +<pre><code># create a new stream object +$zip = new ZipStream('example.zip'); + +# then add one or more files + +# add first file +$data = file_get_contents('some_file.gif'); +$zip->add_file('some_file.gif', $data); + +# add second file +$data = file_get_contents('another_file.txt'); +$zip->add_file('another_file.txt', $data); + +# finally, finish the stream +$zip->finish(); +</code></pre> + +<p>You can also set file comments and creation dates, like so:</p> + +<pre><code>$data = file_get_contents('foo.txt'); +$zip->add_file('foo.txt', $data, array( + 'comment' => 'this is an interesting comment', + 'time' => time() - 3600, # created one hour ago +)); +</code></pre> + +<p>Here are the links, enjoy:</p> + +<ul> +<li><a href="http://pablotron.org/files/zipstream-php-0.1.1.tar.gz" title="ZipStream-PHP 0.1.1 tarball.">Download ZipStream-PHP 0.1.1</a> (<a href="http://pablotron.org/files/zipstream-php-0.1.1.tar.gz.asc" title="PGP signature for ZipStream-PHP 0.1.1 tarball.">Signature</a>)</li> +<li><a href="http://hg.pablotron.org/zipstream-php/" title="ZipStream-PHP Mercurial repository.">ZipStream Mercurial Repository</a></li> +</ul> + + |
