class="alignright size-full wp-image-2023"/>When you’re emailing or uploading larger files, it always makes sense to compress them first. This decreases file size and also helps avoid file corruption during transfer. The most common compressed file you will encounter is the zip file, since most operating systems come with a basic utility to quickly zip and unzip files. Creating a small function to upload a zip file to your server and unpack in the process isn’t as complicated as you might think.<br/> <span id="more-2010"></span><br/> First let’s create a simple form that will allow us to browse our computer and upload a zip file.</p><div class="wp_syntax"><table border="0" cellpadding="0" cellspacing="0"><tr><td><div class="code"><pre class="php" style="font-family:monospace;"><span style="color: #339933;"><</span>form enctype<span style="color: #339933;">=</span><span style="color: #0000ff;">"multipart/form-data"</span> method<span style="color: #339933;">=</span><span style="color: #0000ff;">"post"</span> action<span style="color: #339933;">=</span><span style="color: #0000ff;">""</span><span style="color: #339933;">></span> <span style="color: #339933;"><</span>label<span style="color: #339933;">></span>Choose a zip <span style="color: #990000;">file</span> to upload<span style="color: #339933;">:</span> <span style="color: #339933;"><</span>input type<span style="color: #339933;">=</span><span style="color: #0000ff;">"file"</span> name<span style="color: #339933;">=</span><span style="color: #0000ff;">"zip_file"</span> <span style="color: #339933;">/></</span>label<span style="color: #339933;">></span> <span style="color: #339933;"><</span>br <span style="color: #339933;">/></span> <span style="color: #339933;"><</span>input type<span style="color: #339933;">=</span><span style="color: #0000ff;">"submit"</span> name<span style="color: #339933;">=</span><span style="color: #0000ff;">"submit"</span> value<span style="color: #339933;">=</span><span style="color: #0000ff;">"Upload"</span> <span style="color: #339933;">/></span> <span style="color: #339933;"></</span>form<span style="color: #339933;">></span></pre></div></td></tr></table></div><p>Now comes the uploader function:</p><div class="wp_syntax"><table border="0" cellpadding="0" cellspacing="0"><tr><td><div class="code"><pre class="php" style="font-family:monospace;"><span style="color: #000000;
