PHP Fatal error: Using $this when not in object context for script - class

Question

I've got problem:
I have a script that I'm working with and just upgraded to PHP 5.3.
In my kit_parser.php I'm getting the following fatal error:
Fatal error: Using $this when not in object context in /home/sitename/public_html/secure/includes/hooks/kits/kit_parser.php on line 71
This is the section of code it's referencing:
LINE 71---> $this->kit__log_add(array("<b>PHP Warning</b> [$errno] $errstr on line $errline in file $errfile"));
function kit_error($errno, $errstr, $errfile, $errline, $die = false) {
if (1==1){//$this->displayErrors ) {
switch ($errno) {
/* Custom Errors */
case E_USER_ERROR:
break;
case E_USER_WARNING:
break;
case E_USER_NOTICE:
break;
case E_ERROR:
$this->kit__log_add(array("<b>PHP Error</b> [$errno] $errstr on line $errline in file $errfile"));
die();
break;
case E_WARNING:
$this->kit__log_add(array("<b>PHP Warning</b> [$errno] $errstr on line $errline in file $errfile"));
break;
}
return true;
}
return false;
}
Why is the error coming? Nothing found, never seen before in my other scripts. Can anyone help me please?

Answer 1

This error usually means that you're using $this in a static class method. Make sure that the method this code is in is not static. If it is, you should probably be using this syntax instead:
YourClassNameGoesHere::kit__log_add(array("<b>PHP Warning</b> [$errno] $errstr on line $errline in file $errfile"));
