<p>Permits you to compress a directory (and its contents) that already exists somewhere on your server.
|
|||
|
|
Supply a path to the directory and the zip class will recursively read and recreate it as a Zip archive.
|
|||
|
|
All files contained within the supplied path will be encoded, as will any sub-directories contained within it. Example:</p>
|
|||
|
|
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$path</span> <span class="o">=</span> <span class="s1">'/path/to/your/directory/'</span><span class="p">;</span>

<span class="nv">$this</span><span class="o">-></span><span class="na">zip</span><span class="o">-></span><span class="na">read_dir</span><span class="p">(</span><span class="nv">$path</span><span class="p">);</span>
|
|||
|
|
|
|||
|
|
<span class="c1">// Download the file to your desktop. Name it "my_backup.zip"</span>

<span class="nv">$this</span><span class="o">-></span><span class="na">zip</span><span class="o">-></span><span class="na">download</span><span class="p">(</span><span class="s1">'my_backup.zip'</span><span class="p">);</span>
|

|
|
</pre></div>
|
|||
|
|
</div>
|
|||
|
|
<p>By default the Zip archive will place all directories listed in the first parameter
|
|||
|
|
inside the zip. If you want the tree preceding the target directory to be ignored,
|
|||
|
|
you can pass FALSE (boolean) in the second parameter. Example:</p>
|
|||
|
|
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$path</span> <span class="o">=</span> <span class="s1">'/path/to/your/directory/'</span><span class="p">;</span>

<p>The Zip class caches your zip data so that it doesn’t need to recompile the Zip archive
|
|||
|
|
for each method you use above. If, however, you need to create multiple Zip archives,
|
|||
|
|
each with different data, you can clear the cache between calls. Example:</p>

|
