Simple $ question

How do I merge several variables into a single variable?

I think this demos what I want to do, but this doesn't quite work:

$FDATE = '$YEAR-$MONTH-$DAY';

For example if $YEAR = 2000, $MONTH = 01, and $DAY = 28, I want it to form into 2000-01-28 in $FDATE

Help appreciated, thanks!

$FDATE = $YEAR . "-" . $MONTH . "-" . $DAY;

Or, your original line would work fine with DOUBLE quotes. That way you don't have to mess with periods (concatenation).

$FDATE = "$YEAR-$MONTH-$DAY";

Single quotes mean literal, so anything inside them will turn out as is. PHP will interpret var's embedded in double quotes.
