[PHP] How to address __FILE__ constant in extensions?
Hi there, i am not getting it. How can I read out the magical __FILE__ constant inside an _extension_ (a loadable module) ? Its not in symbol_table, so where is it? bg Sam -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Im programming for a few years now in PHP. After trying to use classes i
dont see their point either. In most cases if i need a class-like structure
i do something like this:
function thing_new() {
return ++$GLOBALS['thing_resource'];
}
function thing_put($stuff, $res=NULL) {
if (is_null($res)) $res = $GLOBALS['thing_resource'];
$GLOBALS['thing_stuff'][$res] = $stuff;
}
function thing_get($stuff, $res=NULL) {
if (is_null($res)) $res = $GLOBALS['thing_resource'];
return $GLOBALS['thing_stuff'][$res];
}
Because there is no constraint to be more OO like in Java it doesnt makes
sense. And this way you are more flexible.

Sure i have to add and take care of the namespaces myself, but thats it and
the amount mental work compared to designing a class is imho lesser in my
way. And most times only 1 object of a class gets instanciated, which is to
much overhead in an application. And then u dont even need my construct.
And if you dont create an object and call the function in an static way
(via ::), then the whole benefit of the associated data is gone anyway and
the only thing you have is the namespace. So i dont give the Parser the
challenge of preparing a class representation and keep it simple. And at
last: no more copied objects.

Ok i just assumed that, but good to know for sure.

That is the only benefit. But it's not OOP. If you need namespaces and can't take care of them w/o misuse of a semi-OOP construct youre not any more efficient with it. >> Is there any performance benefit one way or the other? > > Programmer performance? > >> I used EZ_Sql which is cool but didn't seem to speed things up in >> comparison to the said include file. >> Still don't see the beef. > > Execution speed isn't all that matters.

Don't take it hard, but If you had ever been in computer-science [school|college|...] you would know that speed is all that matters. bg Sam -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
