nice!
This would allow me to have $str loaded with all kinds of variables and
not have to do a str_replace with each (assuming the quote business is cool)
Why did you have the double \\?
> eval('$str_expanded = "' . str_replace('"', '\\"', $str) . '";');
Isn't the following equivalent?
eval('$str_expanded = "' . str_replace('"', '\"', $str) . '";');
