1. classname are case-insensitive (at least in all the builds I have running)
but since 5.0.1 (IIRC) the engine honors your case when using get_class(),
in the past the class name was always returned lowercase. so:
php -r 'class Test {} $t = new Test; if ($t instanceof test) { echo "yeah!\n"; } echo get_class($t),"\n";'
will echo:
yeah!
Test
2. methodnames are the same as functionname with regard to case-sensitivity
3. constants (and class constants) are case sensitive.
....somebody beat me with a virtual stick if I am wrong!
