[Richard Feynman talks about what Artifical Intelligence is]

in the mentoring Zoom meeting today, the topic of Ai came up again.

it looks like $data in line 172 is set as a string earlier in the code.  While you do not have to explicitly set data types for most stuff in PHP, IF $data was set to a string value, you cannot then use it as an array in that way.  That line appears to be saying `add a new entry in this array at the end with the value ...` and the array you are setting.

If you are not using $data earlier, then simply get rid of the square brackets after that.

If that doesn't solve it, I might be able to help if I saw more of the code
