    how to check if variable is an array?

    Hi,

    I'm using php 4.4.4. How do i check if a given variable is an array
    or simply a scalar?

    Thanks, - Dave

      is_array ?

      there are others:
      is_float()
      is_int()
      is_string()
      is_object()

                  Just pointed it out, as it's normally no problem in PHP to juggle types as
                  one goes, but the difference between scalar & non-scalar is often
                  significant for functions, so a simple test is_scalar() offcourse beats
                  (!is_array()&&! is_object()&&!i s_resource()) or (is_string()||i s_float()).
