Hello Yury, I offer the following clarification, hopefully: all($stuff == 0) # checks if every element in $stuff is zero all($stuff == 5) # checks if every element in $stuff is 5 all($stuff) # checks if every element in $stuff is boolean true all($stuff) == 0 # checks if it is not the case that every element in $stuff is boolean true !all($stuff) # same as above
Hopefully that clarifies what's going on. I think it's clearest if the boolean condition is *inside* the parentheses of the all() function call, as in the first two examples.
