Hi,
define('MYCONST', 'something');
$my = 'my';
$const = 'const';
is it possible to get the value of MYCONST using variables $my and
$const_

I don't really see how you can? The only correlation at all is that the
two variables use the same letters combined as their values as the name
of the constant but in a different case. Variables and constants in PHP
are case-sensitive.
Why are you trying to do this anyway? Perhaps there's a better way than
what you are trying to do.
Thanks,

<?php
define('PERFIX', 'dbperfix_');
define('DB_MYTABLE', PERFIX . 'mytable');
abstract class Database {
private static function table_name() {
$table_name = strtolower(get_called_class());
return constant('DB_' . strtoupper($table_name));
}
public static function return_query() {
return "select * from " . static::table_name() . " where
something='value'";
}
}
class MyTable extends Database {
}
echo MyTable::return_query();
?>
i know i could just do return PERFIX . $table_name. - i'm using it that
way. i was just curious if the other way is possible. might come handy
some day!

this is better:
<?php
define('PERFIX', 'dbperfix_');
define('DB_MYTABLE', PERFIX . 'mytable');
abstract class Database {
private static function table_name() {
return constant('DB_' . strtoupper(get_called_class()));
}
public static function return_query() {
return "select * from " . static::table_name() . " where
something='value'";
}
}
class MyTable extends Database {
}
echo MyTable::return_query();
?>
I'm jumping a few steps here, but you may be interested in looking at this
pattern :)
http://java.sun.com/blueprints/corej2eepatterns/Patterns/DataAccessObject.html
i'm using also somekind of patter... don't have a name for it!
You're half way to building a DAO pattern / an ORM, been down this road
several times myself and recognise it well.
<snip-code looks cool, no feedback - sure you'll figure it out as you
hit things over the coming days and weeks ;)
PHP 5.3 is fun! With namespaced i can autoload all classes in different
folders as well using namespace corresponding to the path to the class file!
But best of all, you're playing, learning, hacking and using the latest
versions of your tools, so all credit to you and hope you have fun
finding your own way - it's a wonderful thing when you read a book
written by a coding legend in years to come and recognise what they are
saying, and moreover have came to the same conclusions yourself (or even
better you can disagree and back up your reasons why).
Good luck & keep going, you're doing great.
Nathan
