The visual quality of all examples are very impressive, but...
I didnt found good examples of data manipulation. I am a web developer and we know today the market is almost all dominated with server side scripts, php or asp.net mostly.
I would really love to see examples of interplay of sencha tech and php with CRUD. Anyone can post a link for it? Is it possible this interplay? I will do another clue about importance of server processing. Any client processing is prone to have its security cracked easily... well, someone have any link for ExtJj4+PHP ?
