$test is a string variable, not an array. To add elements to an array,
either use $varname[], array_push(), or array_unshift().
BTW, when an error message says that a variable is not the right type, this
is a good time to use gettype() and/or var_dump() in order to check that
the variable really has the type and value(s) what that you expect.
