Try to imagine calculation tree for the entire expression. if the depth is over 15 it wont be evaluated by inspection

I don't know how to imagine calculation tree for this expression. Can you explain it for ordinar php developers? Or change this tooltip to provide more simple explanation, which ordinar php developers can understand.
