Fatal error: Using $this when not in object context in PHP

Whenever you got this error check the following:

1. Make sure the $this-> is used inside the object and referring to the class’s and inherited non-static members.

2. Make sure the called members of the object are properly addressed as static or member/function variables

Do you know the different different post types?

Here is an example for the second one.

Assume you have the following object

class Example
{
   function getExampleText()
   {
      return "Example Text";
   }
   static function getStaticExampleText()
   {
      return "Static Example Text";
   }
}

While accessing, if the code tries something like this one,

$example = new Example();
Example::getExampleText(); //Trying to access non-static as static

Then you would have the error

The superclass “javax.servlet.http.HttpServlet” was not found on the Java Build Path
