I'm at a pretty early stage of learning php and I'm looking to be able
to examine a string and tell which each character in that string is -
a letter or a number. I've tried php.net but I'm either asking the
wrong questions or I don't understand the answers.
Any help gratefully received.

ctype_alpha($te xt); // alphabetic within current locale
ctype_digit($nu m); // digits 0-9

Thank you, that looks like what I wanted. I'll be checking it out
later on this week, but does the ctype_aplha() identify spaces, too?

ctype_alpha does not accept spaces.
