[PHP] passing by reference via the variable arg list

[Trevor Dowling]

Can anyone help with this?

I am relativly new to PHP and am trying to use variable numbers of
parameters to functions using the func_get_arg().
However, I am unable to determine the correct syntax for passing by
reference via the variable arg list.

/* This Works Fine */
function Foo($Index, &$TxtString)
{
 $TxtString = "NewString";
}


/* However: how do you pass by reference using a variable number of
parameters */
function Foo()
{
 if(func_get_arg(0) == 3)
 {
  /* Can you have a variable in function foo that allows access by
reference? */
  $TxtString = func_get_arg(1);

  $TxtString = "Second New String";
 }
}


function FooTest()
{

 $StringTest = 'Test';

 Foo(2);

 Foo(3, $StringTest);

 echo ("$StringText");
}
