How to find average of seconds in php -

I'm displaying some photos in the iPhone app. If users view information about the image, then I will send the user my SQL table. How can now get the average of seconds for each picture.

You do not need to do this in PHP to work on the database using the overall work You can get:

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.

This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
