Creating a JSON-Array from data got by Select query from MySQL Database
<p>I am trying to transform the result of an SQL Select-Query, to a JSON-File in a format readable by DataTables. </p>

<p>Now I am getting the results transformed to this form: </p>

<pre><code>{  
   "data":[  
      [  
         "pIdWrittenHere1232131231",
         "sNameWrittenHere",
         "lNameWrittenHere",
         "http://Some.pLogUrl.writtenHere.com/",
         "incentivWrittenHere",
         "https://someDetailsUrl.WrittenHere.com/
      ],
       [  
         "pId2WrittenHere1232131231",
         "sName2WrittenHere",
         "lName2WrittenHere",
         "http://Some.pLogUrl.writtenHere.com/",
         "incentiv2WrittenHere",
         "https://someDetailsUrl.WrittenHere.com/
      ]
    ]
}
</code></pre>

<p>Here is the php I am using to transform them actually: </p>
