    <p>I'm having a very interesting problem with PHP. The following code grabs a line from a text file, decodes that text as json into an stdClass object, then puts it into an array conditionally on one of its properties. </p> <pre><code>$fileStream = @fopen($fileName, 'r+'); $lastUpdate = $_POST['lastUpdate']; if($fileStream) { $eventArray = array(); while (($buffer = fgets($fileStream, 8192)) !== false) { $decodedEvent = json_decode($buffer); echo var_dump($decodedEvent); if ($decodedEvent-&gt;timestamp &gt; $lastUpdate) { array_push($eventArray, $decodedEvent); } } $jsonEvents = json_encode($eventArray); echo $jsonEvents; } else { $fileStream = @fopen($fileName, 'a'); } @fclose($fileStream); </code></pre> <p>This produces the error:</p> <pre><code>Notice:Trying to get property of non-object in C:\****\gameManager.php on line 23 </code></pre> <p>I know that the object is valid in multiple ways. For instance, var_dump is producing this:</p> <pre><code>object(stdClass)#1 (3) { ["name"]=&gt; string(4) "move" ["args"]=&gt; array(3) { [0]=&gt; int(24) [1]=&gt; int(300) [2]=&gt; int(50) } ["timestamp"]=&gt; float(1352223678463) } </code></pre> <p>If I try to access $decodedEvent using <code>$decodedEvent["timestamp"]</code> I get an error telling me that objects can't be accessed as arrays.</p> <p>Also, it does indeed echo proper json, which can only be encoded from a proper object:</p> <pre><code>[{"name":"move","args":[24,300,50],"timestamp":1352223678463}] </code></pre> <p>Am I missing something here, or is PHP misbehaving? Any help is greatly appreciated.</p> <p><strong>EDIT</strong>: Here is the input from the file:</p> <pre><code>{"name":"move","args":[24,300,50],"timestamp":1352223678463} </code></pre>

    2. COAh, that was an error on my part. Edited to reflect access as an array. `if ($decodedEvent->timestamp > $lastUpdate) {`

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.
