help with sort problem

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I hope someone might help me with a little puzzle... I have bunch of db results and one of the fields is 'name', I want to see if there are 2 parts to it like FirstName LastName and if so order by the last name. I can see explode() being the php function I need here but am a little lost as to what will happen if there is only one word in the name var. If someone can suggest what I might do that would be great! many thanks... - -- Nick Wilson // www.explodingnet.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) iD8DBQE83pbjHpvrrTa6L5oRAv5XAJsFAXLb0puFyeknXoaGL7rYUHGxVACdHxt8 ej2/Y56p75z5jZ43DvSbDzo= =8rzj -----END PGP SIGNATURE-----
