Just wondering, how would I code a class that worked as follows:

PHP Code:

<?

$do = new DoStuff;



$foo = $do->do_something()->do_something_else();

?>

OR:

PHP Code:

<?

$do = new DoStuff;



$foo = $do->do_something();

$bar = $foo->do_something_else();

?>

I am fammiliar with creating a basic class, but not having one object on top of another one. I'm not even sure if PHP supports this like perl does (this type of construct is very common in perl, but I have not seen it in php).

you mean you have a function inside another function and you want to call the child function !? why did you make it like this ? it's just not needed ..
try calling them like this :

PHP Code:

$do = new DoStuff;



$foo = $do->do_something();

$foo = $do->do_something_else(); 

or you could call these functions without creating the object !! the opereator :: does this :

PHP Code:

CLASS car {

 function tyre () {

   echo'what ever';

 }

 function door() {

   echo'this door is bad !';

 }

}

//calling them with the class name without creating the object :

car::tyre();

car::door();



//or you could just create the object and call it :

$mycar = new car;



$mycar->trye();

$mycar->door(); 

the good thing about :: is that if your class is large you can use this operator to run the functions without processing the whole object ...

what ever was the level of the function you can just call it ..

Hi,

Thanks for that, but basic classes and objects like that aren't what I want.
I was wanting to write a basic socket class for reading writing to an array of sockets (up to a dozen open sockets at once, hence the need for my own functions). If this cannot be done in PHP, I'll try perl instead, as I know for certain this kind of construct is supported. Maybe this example clarifies things:

PHP Code:

<?



require ("./socket.php");



$hostname[0] = 'foobar.com';

$port[0] = 123;



$hostname[1] = 'foo.com';

$port[1] = 456;





$data = "some data here";



$socket = new Socket;



$sockets[0] = $socket->connect($hostname[0],$port[0]);

$sockets[1] = $socket->connect($hostname[1],$port[1]);



$sockets[0]->send($data);

$sockets[1]->send($data);



$result[0] = $sockets[0]->read(1024); // Read up to 1024 bytes.

$result[1] = $sockets[1]->read(1024);



?>
