Sort on server side (PHP/MySQL) or on clinet side (js)?

[ashd]

I have a JS application, which communicates with the server only by API calls. All the data for the app is recieved via API calls. Is it better to sort table-like data on client side (js), or server side (PHP/MySQL) ? Is it possible to sort reliably with js ? I'm keen to sort on client side, but not sure if this reliable enough.
