User class not found - helmut - 11-02-2015
Hello,
in the folder *application/libraries* I installed a script "Utilities.php", with a class "Utilities".
Instancing the class is no problem, also reflection displays all methods.
but when I pass the object to the constructor of another class,
I get the strange error
Severity: Error
Message: Class 'CI_Utilities' not found
Filename: core/Common.php
Line Number: 196
Why does CI create a class CI_Utilities from a user class?
What is wrong here?
thanx for your help, Helmut

How do you load this class in your code? with load->library('Utilities') or autoload ?
1 advice - to prevent duplication of CI Class names try adding prefix or suffix to your class : Utilities_library..

with:
$this->load->library('Utilities');

This should only be done if you want to extend native CI-Libraries.

Having looked into the sourcecode of Common.php, I have the impression that there is a bug.

How and to which class are you passing the utilities or user object?
Did a quick test with two libraries. One I called Utilities and the second one Test.
I then did this:
PHP Code:
$this->load->library('Utilities');
$this->load->library('Test', array($this->utilities));
Got 0 errors with this. So Utilities is not a reserved name within CI nore does CI change it in anyway that I chould see.

Thanks,now I see that the problem is in the instanciation of the other class (Test in your example), which I did not perform correctly.
But now after the commands
$this->load->library('Test', array($this->utilities)); //here no error occurs
--
$vars = get_object_vars($this->Test);
var_dump($vars);
I get the error
Message: Undefined property: Test::$Test
and
Message: get_object_vars() expects parameter 1 to be object, null given

As far as I know, you should use $this->test (in lower case)
Also get_object_vars and var_dump should be called outside the Test class.

@pdthinh is correct it should be
PHP Code:
$vars = get_object_vars($this->test); // test in lower case!

Unfortunately the error occurs in either version, lower AND upper case
