Objects & Includes

[Anon]

I've got a site wide config file containing CONSTANTS and such of widely used paths and variables.

Is there an efficient way to call CONSTANTS and such from within a class? I'm customizing class.FastTemplate and I want to use variables from my config file in my class methods....

Thanks

I think I need a vacation

"Constants" meaning variables defined using define()? Those are relatively easy to do: you can call them anywhere in any file :-)

Ex:

define("SOMEVAR", FILE);

will make SOMEVAR accessible in any file or function, no need for global commands.

Ex:

function foo($bar) {
echo SOMEVAR . $bar;
}

will output the contents of SOMEVAR, in this case the value of FILE (a php constant). Note, constants in this manner do not need a $ in front of them.

I was actually trying to create a custom class and import the constants into that class' scope along with other global config data(i.e., common paths). Now I now that class' should be encapsulated to ensure their portablilty and inheritance, but I'm new to PHP and I'm not sure if you can import files into the scope of a class. Like I said, i need a vacation and this may be a very simple question...

Thanks for responding

"I'm not sure if you can import files into the scope of a class"

Umm, have you tried? having "include('constants.php');" in your class definition sounds like a plausible construct to me. If I understand PHP's documentation aright, it effectively interpolates the contents of a file right into the spot where the include() call sits (escaping from PHP into HTML mode notwithstanding), so that

----localconstants.php------
<?php
$foo='bar';

?>

----classdef.php------------
...stuff...
include('localconstants.php');

...ffuts....

is entirely equivalent to
----classdef.php------------
...stuff...
$foo='bar';

...ffuts....

Is this what you want? There's little point in them being define() constants, as they're global anyway.
