<p class="first admonition-title">Note</p>
<p class="last">Paths are almost always relative to your main index.php file.</p>
</div>
<p>Sub-folders contained within the directory will be mapped as well. If
you wish to control the recursion depth, you can do so using the second
parameter (integer). A depth of 1 will only map the top level directory:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$map</span> <span class="o">=</span> <span class="nx">directory_map</span><span class="p">(</span><span class="s1">'./mydirectory/'</span><span class="p">,</span> <span class="mi">1</span><span class="p">);</span>
</pre></div>
</div>
<p>By default, hidden files will not be included in the returned array. To
override this behavior, you may set a third parameter to true (boolean):</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$map</span> <span class="o">=</span> <span class="nx">directory_map</span><span class="p">(</span><span class="s1">'./mydirectory/'</span><span class="p">,</span> <span class="k">FALSE</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
</pre></div>
</div>
<p>Each folder name will be an array index, while its contained files will
be numerically indexed. Here is an example of a typical array:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">Array</span> <span class="p">(</span>
<span class="p">[</span><span class="nx">libraries</span><span class="p">]</span> <span class="o">=></span> <span class="k">Array</span>
