    <p>I'm using a php library from <a href="https://sourceforge.net/p/wowarmoryapi/home/Home/" rel="nofollow noreferrer">https://sourceforge.net/p/wowarmoryapi/home/Home/</a>. It pulls json data from battle.net and stores it in my database for cache reasons.</p> <p>code to get json from db (I'm not sure if it's still considered json at this point):</p> <pre><code>$data = $con-&gt;query('SELECT Data FROM wa_guilds'); </code></pre> <p>I use the following code to see the data:</p> <pre><code>foreach($data as $row) { echo "&lt;span style='color:#ff0099'&gt;"; var_dump($row); echo "&lt;/span&gt;"; } </code></pre> <p>which looks like this minus the errors, that's from another code: <img src="https://i.stack.imgur.com/x3ial.jpg" alt="pink text is the dump"></p> <p>I've tried various methods, mostly from this site to show my data in a way that's easy to read but I always get error. </p> <ol> <li>This is definitely an object. <code>if (is_object($data)) { echo "yay!"; }</code> &lt;--this works</li> <li>Once I use <code>$decodedjson = json_decode($data);</code> it's no longer an object and I can't seem to print the results to see what it looks like. var_dump($decodedjson) returns NULL</li> </ol> <p>Finally, when I use the following code:</p> <pre><code>foreach ($data as $da){ echo $da['Data']['character']['name']; } </code></pre> <p>returns <b>Warning: Illegal string offset 'character'</b></p> <p>and:</p> <pre><code>foreach ($data as $da){ echo $da['character']['name']; } </code></pre> <p>returns <b>Notice: Undefined index: character</b></p> <p>I don't understand what I'd doing wrong, or right. Do I need to somehow turn $data into a string?</p> <h2>NEW CODE</h2> <pre><code>$sth = $con-&gt;query('SELECT Data FROM wa_guilds'); $sth-&gt;execute(); $data = $sth-&gt;fetchAll(PDO::FETCH_ASSOC); foreach($data as $row) { foreach($row as $r) { $myData = json_decode($r, true); echo "&lt;span style='color:#ff0099'&gt;"; var_dump($myData['Data']); echo "&lt;/span&gt;"; } } </code></pre> <h2>NEW ERROR</h2> <p>NULL NULL</p>

    1. COWhat gives a `var_dump($data);` right after the `$data = $con->query()` line? I'm guessing that you are trying to loop on a query reference, instead of the query results.

    2. CO@FrostyZ that's all the pink text in the photo. It's so I can read and make sure that someone was actually in the database. Oh yeah, it's in a loop because someone suggested that, I just never changed it. Oh, when I take it out of the loop I get this back: `object(PDOStatement)#2 (1) { ["queryString"]=> string(26) "SELECT Data FROM wa_guilds" }`

    3. COCan you post part of the result of `var_dump($data)`?

Querying!

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
