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.

Sean
