    <p>I want to build a Json output to list folder structure inside ExtJS tree panel. The structure should be the equivalent of this array in Json:</p> <pre><code>Array ( [text] =&gt; . [children] =&gt; Array ( [0] =&gt; Array ( [text] =&gt; files [children] =&gt; ) [1] =&gt; Array ( [text] =&gt; folder 1 [children] =&gt; ) [2] =&gt; Array ( [text] =&gt; New directory [children] =&gt; array( [0] =&gt; Array ( [text] =&gt; sub_1 [children] =&gt; array( [0] =&gt; Array ( [text] =&gt; sub_1_1 [children] =&gt; ) [1] =&gt; Array ( [text] =&gt; sub_1_2 [children] =&gt; ) ) ) [1] =&gt; Array ( [text] =&gt; sub_2 [children] =&gt; ) ) ) ) ) </code></pre> <p>i made this function which shows the structure by going through PHP Manual and examples</p> <pre><code>listFolders('../file_uploads/'); function listFolders($dir){ $dh = scandir($dir); echo '&lt;ul&gt;'; foreach($dh as $folder){ if($folder != '.' &amp;&amp; $folder != '..') { if(is_dir($dir.'/'.$folder)){ echo '&lt;li&gt;'.$folder.'&lt;/li&gt;'; listFolders($dir.'/'.$folder); } } } echo '&lt;/ul&gt;'; } </code></pre> <p>this outputs the structure</p> <ul><li>New directory</li><ul><li>sub_1</li><ul><li>sub_1_1</li><ul><li>sub_1_1_1</li><ul></ul></ul><li>sub_1_2</li><ul></ul></ul><li>sub_2</li><ul></ul></ul><li>files</li><ul></ul><li>folder 1</li><ul></ul></ul> <p>I want to know how to convert this output to a array (or the Json) like above?</p> <p><strong>solution</strong></p> <pre><code>print "&lt;pre&gt;"; print_r(listFolders('../file_uploads/')); function listFolders($dir) { $dh = scandir($dir); $return = array(); foreach ($dh as $folder) { if ($folder != '.' &amp;&amp; $folder != '..') { if (is_dir($dir . '/' . $folder)) { $return[] = array( 'text' =&gt; $folder, 'children' =&gt; listFolders($dir . '/' . $folder) ); } } } return $return; } </code></pre> <p><img src="https://i.stack.imgur.com/ODxCJ.png" alt="enter image description here"></p>

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.
