Re: [PHP] passing by reference via the variable arg list

2002-09-24 Thread Marek Kilimajer 

Not possible, but workaround is to pass the variable name and use it as 
a variable variable, but for this the variable needs to be global.

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.

Trevor


/* 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);
}
