Exception class in PHP (is this magic?)

[enridp]

Hi ! I was seeing the Exception class defined in basic.php and I found that all the methods are final and without body:

final public function getMessage () {}

But if I call MyCustomException->getMessage() I get the message.

How does it works??

The class likely extends the built in Exception class.

I didn't understand you thorpe, I'm talking about Exception class, the built in PHP class.

That class is defined in basic.php, and the method is defined as:

final public function getMessage () {}

How can it works then?

Even in php.net there's a comment at the end about that:

http://www.php.net/manual/es/class.exception.php#84617

 

If the method has not definition why when we use ->getMessage() we get the message?

As you just stated. The Exception class is built into PHP so it's not defined in any basic.php file. The class you are looking at within basic.php likely extends the built in PHP Exception class.

Ah, OK, I was pressing F3 in Zend Studio and that take me to basic.php.

Is possible to see the official PHP code for Exception Class?

The Exception class is (like the rest of PHP) written in C. Why do you need to see the code? The manual tells you what it provides.

it was just curiosity, I was pressing F3 and I found that file (basic.php) which confused me. Thanks thorpe !
