Constant in a class - El Forum - 01-31-2009

Hey there

I wonder how I could access a constant in a class/library from outside through CI's loading mechanics:

Code:
[...]

//library lib_test.php

const SOME_CONSTANT    = 0;

Now, in a controller, this doesn't work:

Code:
$this->load->library('lib_test'));

echo $this->lib_test::CONSTANT;    //Parse-error

echo $this->lib_test->CONSTANT;    //No parse-error, but neither a result

Any suggestion how to access constants (or class-vars)?

From my reading of it you'd want to use:

Code:
echo lib_test::CONSTANT

The first method you've attempted is fine in php 5.3 apparently. The second will read the object variables. You can read more on object constants in the [url-http://uk.php.net/manual/en/language.oop5.constants.php]php manual[/url]

You should also note that libraries should be capitalised...User guide
