title: Returning SQL Blob from PHP JSON
body: <p>I've read many posts regarding PHP/JSON blob processing, but, none seem to provide a clear cut example on how to proceed.  I am trying to communicate with an SQL database on a server.  The table in question has a medium blob field.  I use PHP and JSON to grab the data and display it on an Android phone.  I have no problem with the non-blob data.  I can grab it and display it with no problems.  However, the blob data always returns as "null" via JSON.  I understand that JSON does not directly support binary data, but, my question still remains, how do I access the blob data from the Android system?  The blob data in question is mostly text files (ie. .PDF, .DOC, etc.).  I have no control over the SQL table.  More importantly, how do I get the blob field packaged with the rest of the data so I can process it on the Android platform?  Any help would be greatly appreciated.</p>
