Classes with set_error_handler

[CarbonCopy]

I am designing an application which I want to have custom error reporting, and I am using a class. However, when using self:: I get this error:

 

Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /www/.............../error.inc.php on line 38 

 

And here is error.inc.php

When using the self keyword in combination with a class property, the property does need to be prefixed with a dollar sign.

 

ex:

// Old (ERROR)
if ( self::cms->database->connected )

// New (No Error)
if ( self::$cms->database->connected )

I see this error on lines

Well that fixed that problem, so thank you. Now I get an error for the class calling that method.
