I am well versed in coding with xhtml which requires all lower case and am pretty much a newbie at PHP so that is why I am asking this question. is this acceptible if ($_post [sender_email] == "") or does at have to be if ($_POST [sender_email] == "") in short, do uppercase and lowercase always have the same meaning. thx,

PHP is case-sensitive. UppERCase is NOT the same as uppercase. HTML is not case sensitive only because browsers are forgiving.

PHP variables are case-sensitive. PHP FUNCTIONS are not. You're on your own figuring out if class names/methods are/aren't case-sensitive this week. :-v

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!
