Three different topics, perhaps suited to three seperate emails, but I'll cover them all in one.
Firstly, something regarding accessing form/query string variables, on diffferent versions of PHP. Starts to become a nightmare, but you also want to make sure you _aren't_ requiring register_globals to be on... so what I do; function Form($var = null) { if (function_exists('version_compare')) // added in 4.1.0 { return @$_POST[$var]; } global $HTTP_POST_VARS; return @$HTTP_POST_VARS[$var]; } then just $variable = Form('field'); you can adapt the code for the other various http variable arrays etc. I have encapsulated it in a class, and also, to remove the call to the function_exists function every time I attempt to get variable define('MY_PHP_VERSION', function_exists('version_compare')); then the if statement becomes if (MY_PHP_VERSION) { Now, a couple of other things to discuss. can anyone else confirm my conclusion; define('MYSTRING', 'Hello World'); for ($i = 0; $i < 5000; $i++) { echo MYSTRING; } class Msg { function MyString() { return 'Hello World'; } } for ($i = 0; $i < 5000; $i++) { echo Msg::MyString(); } that creating a static class, with static members, and calling those, instead of using define() variables, is actually faster? thirdly, for ($i = 0; $i < 5000; $i++) { echo $i; } $i = 5000; while ($i--) { echo $i; } that the decrementing while loop is actually faster than a for loop? btw I'm aware that a decrementing while loop can not be a replacement for every for loop situation, but there are times when you can use it instead, and from what I can see, its faster. Hope I made sense. I'm in a rush! Also my first post to the list for about 4 years! These things could have been discussed already so I apologise, just in case.
