Hi Robin

Many thanks for this,

how would one extend this to support the following:
$str = "insert into userComment (userID, userName, userSurname) values (0,
'Leon', 'mcDonald')";

one does not want

$str = "insert into user_comment (user_id, user_name, user_surname) values (0,
'Leon', 'mc_donald')";

unfortunately lookbehind assertions does not support non-fixed length chars so
/(?<=(?<!')[a-z])([A-Z]+)/e will work for 'mDonald' but the following will not
work.

/(?<=(?<!')([a-z]+))([A-Z]+)/e

Any ideas?

Many thanks
