Note Submitter: nutbar at innocent dot com ---- A correction to skippy's comment: "...you can use either ${ or {$ to open the curly expression ie. "${var}" and "{$var}" are equivalent." Is incorrect. For simple variables, such as in the example quoted yes both function and yeild the expected result. However, when dealing with array variables like $array['key'], doing "${array['key']}" will yeild errors or unexpected results. The correct formatting is "{$array['key']}".
