    <p>Got it, thanks to you guys!</p> <pre><code>// Get a request from i.e. a webpage (this is a webservice) $jsonArray = file_get_contents('php://input'); // put the JSON-Data into an array $jsonData = json_decode($jsonArray, true); // You can simply choose the entry-points. As they do not change for me, they are hardcoded in here, else you had to use something like a for-loop to extract them $jsonConnect = $jsonData['connected']; $jsonLocation = $jsonData['location']; $jsonConfigured = $jsonData['configured']; // walk through the JSON-Data and extract the values, although the array has more than 2 levels, you can select your entry-point and walk from there on, which makes this quite easy for($i = 0; $i &lt; count($jsonConfigured); $i++){ // keyMgmnt itself is an array and I want to concatenate all of its values and put it into a single field in my MySQL-DB, so implode() is used $keyMgmnt = implode(",", $jsonConfigured[$i]['keyMgmnt']); $grCiphers = implode(",", $jsonConfigured[$i]['grCiphers']); $ssid = $jsonConfigured[$i]['ssid']; $bssid = $jsonConfigured[$i]['bssid']; // from here on I simply put the variables into my MySQL-DB $sql_configured = "INSERT INTO configured (keyMgmnt, grCiphers, ssid, bssid) VALUES ('$keyMgmnt', '$grCiphers', '$ssid', '$bssid')"; mysql_query($sql_configured) or die ("Failure in configured"); } $sql_connected = "INSERT INTO connected (rssi, speed, ssid, bssid) VALUES ('$jsonConnect[rssi]', '$jsonConnect[speed]', '$jsonConnect[ssid]', '$jsonConnect[bssid]')"; $enterConnected = mysql_query($sql_connected) or die("Failure in connection!"); $sql_location = "INSERT INTO location (lat, prov, lon, acc) VALUES ('$jsonLocation[lat]', '$jsonLocation[prov]', '$jsonLocation[lon]', '$jsonLocation[acc]')"; $enterLocation = mysql_query($sql_location) or die("Failure in location!"); </code></pre> <p>Thanks again!</p> <p>Case closed.</p> <p>PS: The structure of the JSON-Data. You get it by using "print_r()" or "var_dump()".</p> <pre><code>( [id] =&gt; bf75b277-169b-49da-8ab1-b78b80f51b43-e25c7f28b3 [ts] =&gt; 1372751172664 [connected] =&gt; Array ( [ssid] =&gt; eduroam [bssid] =&gt; 00:0f:f7:eb:08:81 [rssi] =&gt; -62 [speed] =&gt; 54 ) [configured] =&gt; Array ( [0] =&gt; Array ( [ssid] =&gt; eduroam [bssid] =&gt; null [keyMgmnt] =&gt; Array ( [0] =&gt; 2 [1] =&gt; 3 ) [grCiphers] =&gt; Array ( [0] =&gt; 0 [1] =&gt; 1 [2] =&gt; 2 [3] =&gt; 3 ) ) [1] =&gt; Array ( [ssid] =&gt; foobar [bssid] =&gt; null [keyMgmnt] =&gt; Array ( [0] =&gt; 0 ) [grCiphers] =&gt; Array ( [0] =&gt; 0 [1] =&gt; 1 [2] =&gt; 2 [3] =&gt; 3 ) ) ) [location] =&gt; Array ( [prov] =&gt; network [lat] =&gt; 52.3793203 [lon] =&gt; 9.7231332 [acc] =&gt; 22.777 ) ) ( [id] =&gt; bf75b277-169b-49da-8ab1-b78b80f51b43-e25c7f28b3 [ts] =&gt; 1372751172664 [connected] =&gt; Array ( [ssid] =&gt; eduroam [bssid] =&gt; 00:0f:f7:eb:08:81 [rssi] =&gt; -62 [speed] =&gt; 54 ) [configured] =&gt; Array ( [0] =&gt; Array ( [ssid] =&gt; eduroam [bssid] =&gt; null [keyMgmnt] =&gt; Array ( [0] =&gt; 2 [1] =&gt; 3 ) [grCiphers] =&gt; Array ( [0] =&gt; 0 [1] =&gt; 1 [2] =&gt; 2 [3] =&gt; 3 ) ) [1] =&gt; Array ( [ssid] =&gt; foobar [bssid] =&gt; null [keyMgmnt] =&gt; Array ( [0] =&gt; 0 ) [grCiphers] =&gt; Array ( [0] =&gt; 0 [1] =&gt; 1 [2] =&gt; 2 [3] =&gt; 3 ) ) ) [location] =&gt; Array ( [prov] =&gt; network [lat] =&gt; 52.3793203 [lon] =&gt; 9.7231332 [acc] =&gt; 22.777 ) ) </code></pre>

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.

SQuiL has stopped working due to an internal error.

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