Oh, I came from a VB.NET background from 4-5 years back but must've forgotten how the more simple things were done.
A backslash is an escape entity, Well, best I show you a tutorial on them:

If you're using double quotes within double quotes, they need to be escaped from the current context, Such as:
print "This is a double quote: \" <---";
Dollar signs have precedence in double quotes, so variable can be displayed:
$var = "foo";
print "\$var = $var"; //Will print: $var = foo
I'd really recommend looking up some basic PHP tutorials such as in Tizag, As you can trust from an ex-.NET programmer C is much different in its syntax than VB.
