i think it's a waste of time telling him that xD .
PHP generates a dynamic html output .
which means you simply gets a NORMAL HTML OUPTUT .
just like taking an image .
if you were in the backside you could change stuff before taking a picture .
but after you took it , well you cant change anything anymore (well you can download the template and recode it xD )
same goes with SQL (which generates dynamic data from the requested queries and the output will be combined in HTML format ) .
javascript well , you can download it easily , yet it will be useless without all the rest

.
(at least for you ... ) .
