Is there a setting or program for doing strict checking in PHP compilation?

Coming from an objectpascal background with strict type checking, I am
being driven nuts by PHP.

Stuff like using variables without declaring them, case sensitivity of
variables, getting true, false, 0, 1, "" mixed up, missing the $ before
variables etc is really slowing me down.

Is there a way to configure a run-time setting or interpreter setting
that will throw up warnings or declare an error if some of these issues
are present?

I really need an external lint type program or a run-time setting that
will highlight these issues in PHP.

Use === for a strict type checked comparison, and error_reporting(15) to
get the other stuff (or change the setting in your local php.ini or
httpd.conf files).

uninitialized variables will produce a 'NOTICE' exception. Solution would be
to specif error reporting (only) at the start of each script. Set to E_ALL
for testing, something less sensitive for production. Or write your own
error handler.

C.

Are there any examples of the above techniques?

re: Is there a setting or program for doing strict checking in PHP compilation?

At the beginning of your code, do this:

error_reporting(E_ALL);

when you check if a variable is false, rather than empty, to this:

if (flag === false)

if you want to check if something is storing an integer, you can do
type checking with:
is_integer(i) or is_int(i)

for the $ - your editor should help you identify these. I would
recommend PHP Eclipse.

talking about $, I missed it in all my examples, grrrr
flag should be $flag and i should be $i - sorry about that ... been
programming too much in other languages lately.
