application, it tends to be a drawback. With the result that most PHP scripts
start with <? and end with ?>.
I also like about lua that you can load additional libs during runtime. Your
environment is also not affected by some weird configuration scripts which can
defect your scripts in some weird ways (switching on warning/error levels for
ambiguous operations that are normally ignored).
If your application needs to implement some libraries that are not supported by
PHP (special IO stuff for example) or if you need to do heavy number crunching
that should better be done in some highly optimized C code, you might prefer
Lua as well since it's quite easy to compile and use a custom lib that can be
used in lua.
I also find it easier to debug lua scripts via simple print outputs by changing
certain functions. I.e. I want to know which piece of code is calling a certain
function - simply done in lua by overloading the initial function and do a
stacktrace lookup when it's called.
However it strongly depends on your project you are working on, so maybe you
could write a bit more about in which ways performance / memory footprint is
important for you.
