    Can I use a defined constant like this?

    Hi,

    I have defined a constant like:

    PHP Code:
    define('BASE_URL''http://www.mysite.com'); 
    Can I use the BASE_URL like this and if so how because my example below is not working?

    PHP Code:
    print "<link rel=\"shortcut icon\" type=\"image/x-icon\" href=\". BASE_URL . \"/images/favicon.ico\">" "\n"

    No, constants to not get interpolated within a double-quoted string the way variables do. You'll have to use concatenation (or sprintf()):
    PHP Code:
    define('FOO''Bar');
    echo 
    "Let's go to the ".FOO."."
    "Please give us a simple answer, so that we don't have to think, because if we think, we might find answers that don't fit the way we want the world to be."

    Thanks for the advice,

    I amended it to this and it works fine now:

    PHP Code:
    print "<link rel=\"shortcut icon\" type=\"image/x-icon\" href=\"".BASE_URL."images/favicon.ico\">" "\n"
