RE: [PHP] Problem with HTML Text box and PHP variable.

AFAIK, they are required in XML and XHTML. It's a good habit to get into with regular HTML, also (although, yes, both will work in HTML). [/snip] The best form HTML attributes is within double quotes. This stems from the parent language of all of the mark-up languages, SGML (standard generalized mark-up language). XML and XHTML both more closely follow the rules/recommendations of the parent language. HTML validation engines genrally throw exceptions if attributes are not quoted. It has always been considered good form.
