I'm learning PHP for a Udemy course, but even though the instructors say in the ad that they'll answer the questions within 24 hours, it's been weeks, and they have not answered my question. Very frustrated, so I'm here asking for your help.
I am in the ecommerce module and in my project is giving error in the slim framework as in the image I am sending.
My question is: why the hell is giving code error? How to fix this error?
The project repository is here:
Man, I'm sorry, I forgot to put the file. I had spoken: "(...) as in the image I am sending." but I forgot the image.
