[RESOLVED] Interceptor/string question

[phrosty]

I saw an example in a book recently that I don't fully understand and maybe someone can help clarify for me. The code in question is:

<?php
class Person {
    function __get($property){
        $method = "get{$property}";
        if (method_exists($this, $method)){
            return $this->$method();
        }  

    }

function getName(){
    return "bob";

}

}

$p = new Person();
echo $p->name;

?>

Which mostly makes sense to me, my only issue is this line:

$method = "get{$property}";

what are the brackets for and what do they do in this situation, I have never come across this. I am still learning, so this may be an easier question than I think. Thanks for you help!

The braces are to ensure that $property is evaluated correctly to create the string used to call the function.

Seems like a somewhat useless example when you could just implement __call() to produce the same effect without the string wrangling 🙂
