php - Fatal error: Uncaught TypeError: Cannot access offset of type string on string in

Question

previous question:Fatal error: Uncaught TypeError: filter_var(): Argument #3 ($options) must be of type array

Thanks to the help of some of you I was able to fix part of my site, I put the old questions at the beginning of the post in case you need to look at the previous Bugs to answer me better.

Now there are these new errors, I would be grateful if you would give me further help. Thanks in advance.

I assume these are the latest site troubleshooting bugs..
