[Resolved] Passing a reference

[Catharsis]

Hi all,

Cant seam to find anything on the board already about this so thought Id make a new post.

Is there some way I can check that the user using my API passing in a reference to an object rather than the object itself;

for examlple I want to throw an error if they do this

$class1 = new Foo;
$class2 = new Bar;

$bar->alter_foo($class1);

but not when they do this..

$class1 = new Foo;
$class2 = new Bar;

$bar->alter_foo(&$class1);

The alter_foo function withing class Bar adds things into Foo object and returns true/false for success.

I know in perl you can do

if  (! ref($blah) ) {
  ..do stuff
}

No biggie if I cant do it 🙂

did you try pass by ref in your bar class method?

class Bar
{
function alter_foo(&$foo)
{

}
}

Nope, but that will do it.. I think, will try it out 🙂

okay well that forces the input into a reference no matter what you pass in, which is certainly a solution and seams to work well.

Thanks
