How to test for function accessibility?

[Anon]

I have a gallery class and a administration class that extends the gallery class. The gallery class is just for viewing. Inside the gallery class there is a call to a function that is only present in the administration class. In the gallery class a function is called; 'Add Image'. I can use this function in administration mode but I get an error in gallery mode because the function is not accessible from there (nor do I want it to be). I just want to test for it and display its results when the function is accessible.

class gallery {

function showStuff {
// I want to test for the following functions acessibility so I wont get an error in gallery mode.
$this->addImage();
someOtherStuff();
} // End function showStuff

} // End class gallery

class admin extends gallery {

function addImage {
dostuff;
} // End function addImage

} // End class admin

Any help is greatly appreciated,

Tuurlijk!

Write a method of the same name for the parent class. When an instance of the child class is created the child's method will overwrite the parent's method.

How about this:

class gallery {
var $mode;
function gallery()
{
$mode="gallery";
}
.
.
}

class admin extends gallery {
function admin()
{
$mode="admin";
}

then just test for the value of $mode.

You could also check the Class Functions section in the manual.
