How can PHP developers effectively document and maintain their code to ensure clarity and ease of troubleshooting, especially when dealing with object context-related errors like "Using $this when not in object context"?

When encountering the error "Using $this when not in object context," it means that the code is trying to access a property or method using $this outside of a class context. To resolve this issue, ensure that the code is only using $this within a class method. 

class MyClass {
    private $property;

    public function setProperty($value) {
        $this->property = $value;
    }
}

$obj = new MyClass();
$obj->setProperty("example");
