OOP: returning pointers in php3

[Anon]

How do I return a pointer to the original object (so that I can change its state) from a function in php3?

I.e. I want to do this:
$obj = $root->FindObject($criteria);
$obj->SetValue($some_new_value);

where FindObject should be recursive.

PHP doesn't have pointers as they are thought of in C/C++. You can pass values by reference (actually PHP4 wants you to call them by reference, better for integrity). So when you call by reference you have the actual object/variable instead of making a copy.

To call by reference put the & sign infront of the parameter in your function call.

function my_test(&$test) {
$test++;
}

$test = 1;
print $test;
my_test($test);
print $test;
