PHP Version compatibility issue with EE module

Question

I have created a plugin that is running good in PHP v5.5.x. When I upgrade my PHP version to 7.x it gives me errors.

Code that is suspicious is:

$this->EE =& get_instance();

Error is:

only variables should be passed by reference

Answer 1

As error says, PHP 7 is only allow variables to passed by reference not an instance. You now need to remove that line and replace all $this->EE calls to ee(). That will work for you.

Answer 2

Pretty sure you don't need this in a plugin `$this->EE =& get_instance(); ref https://docs.expressionengine.com/v2/development/plugins.html
