[SOLVED] 2 questions

I'm reading a book about OOP, the author puts "$str = "{$shopProduct->title}:", why the { }

 

Also, is public and var the same thing for php 5+?

The curly brackets are used to surround more 'complex' variables when setting them inline (not jumping out of a string)

 

$str = "{$shopProduct->title}:";
//is the same as
$str = $shopProduct->title.":";
//and on some servers it will work without the curly brackets
$str = "$shopProduct->title:";

 

Using public and private denotes the availability of functions, methods and variables withing an object.

 

var is still used so some examples;

 

public var $foo = "bar";

 

private var $bar = "foo";

 

$foo can be directly accessed from outside of the object where $bar can only be accessed by the object iteslf.
