You could always see if it matches a regular expression that represents
the ascii range you're considering. I.e., ereg('[^a-zA-Z0-9]',$string)
will return true if non-alphanumerics are in the string.
Remember that a string is just a string. Whether the data contained in
it is represented as ASCII or something else is completely a matter of
implementation. ALL 7-bit data can be represented as ASCII. All 8-bit
data can be represented as "IBM Extended ASCII" or whatever you want to
call it. But the string is just a string of bits.
