Hi
I've been aware of an interesting thread on phpbuilder
about the "::" operator. This operator is not yet documented,
nor in operator.xml, nor in classobj.xml.
This may be a good idea to add this. If this was planned already
(some changes seem pretty fresh, aren't they?), just tell me.
Here is the URL

Any opinion?

Of course it's possible. (With php4 at least :))
As in C++, you use the :: operator.
Let's suppose we have a class:
class foo {
var $x;
function foo( $init ) {
$this->x = $init;
}
function print() {
echo "X has a value of:$x";
}
}
And a second class that extends the first one:
class doh extends foo {
var $y;
function doh( $init_x, $init_y ) {
foo::foo( $init_x );
$this->y = $init_y;
}
function print() {
echo "Y has a value of:$y";
foo::print();
}
}
Just try it with a piece of code:
$obj1 = new foo( 'Hi!' );
$obj1->print();
$obj2 = new doh( 'world', 'Hello ' );
$obj2->print();
Hope this help.
:)
