    <p>You can do so by using the <code>zip://</code> syntax instead of <code>Zip::extractTo</code> as described in the <a href="http://www.php.net/manual/en/function.ziparchive-extractto.php" rel="nofollow">php manual on extractTo()</a>.</p> <p>You have to match the image file name and then copy it:</p> <pre><code>if ($entry['size'] &gt; 0 &amp;&amp; preg_match('#\.(jpg)$#i', $entry['name'])) { copy('zip://' . $file_path . '#' . $entry['name'], '/root_dir/' . md5($entry['name']) . '.jpg'); } </code></pre> <p>The above replaces your for loop's if statement and makes your <code>extractTo</code> unnecessary. I used the md5 hash of the original filename to make a unique name. It is extremely unlikely you will have any issues with overwriting files, since hash collisions are rare. Note that this is a bit heavy duty, and instead you could do <code>str_replace('/.', '', $entry['name'])</code> to make a new, unique filename.</p> <p>Full solution (modified version of your code):</p> <pre><code>&lt;?php $zip = new ZipArchive(); if ($zip-&gt;open($file_path)) { for ($i = 0; $i &lt; $zip-&gt;numFiles; $i++) { $entry = $zip-&gt;statIndex($i); // is it an image? if ($entry['size'] &gt; 0 &amp;&amp; preg_match('#\.(jpg)$#i', $entry['name'])) { # use hash (more expensive, but can be useful depending on what you're doing $new_filename = md5($entry['name']) . '.jpg'; # or str_replace for cheaper, potentially longer name: # $new_filename = str_replace('/.', '', $entry['name']); copy('zip://' . $file_path . '#' . $entry['name'], '/myFolder/' . $new_filename); } } $zip-&gt;close(); } ?&gt; </code></pre>

    1. COIt's definitely the better solution to check for duplicates. However, why use a hash algorithm to make file names unique? Hashing each file takes a lot of time in case there are many files in the ZIP archive. I guess a solution that preserves the original filename is preferred, anyway. You could for instance append a consecutive number in brackets to files with the same filename.

    2. COConsecutive number could potentially create duplicates itself, if someone has named files with consecutive numbers at the end :). However, you are right that hashing can be overkill so I have provided an alternative with turning the path into a filename with `str_replace`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
