note 28813 added to language.types.string

This is why this is right: $beer = 'Heineken'; echo "$beer's taste is great"; // works, "'" is an invalid character for varnames echo "He drank some $beers"; // won't work, 's' is a valid character for varnames echo "He drank some ${beer}s"; // works In all these examples, the php code is looking for the variable $beer. In the first one, it works because when it finds $beer's it actually finds $beer and stops at the '. In the second one, it doesn't work because there is no variable designated as $beers. The third one works because the php code reads { and } as specifying what the actually variable is that it should be looking for. The { and } allow you to add onto the variable. -- http://www.php.net/manual/en/language.types.string.php http://master.php.net/manage/user-notes.php?action=edit+28813 http://master.php.net/manage/user-notes.php?action=delete+28813 http://master.php.net/manage/user-notes.php?action=reject+28813
