Thanks. This looks like most of what I was looking for, especially on
curly braces. Never would have thought to look under "strings." At
first glance I didn't see an explanation about when and when not to
use single quotes around array keys. It gets complicated as array
keys are supplied from various sources, i.e. variables, table
columns,form attributes, etc. and given where they come from, the
quote requirement seems to change. I will keep looking in the
article.
