Passing an array as a parameter list

Hi,

In Perl you can pass the elements of an array to a function as actual
parameters, for example

my @a = (1, 2, 3);

f(@a);

which has the same effect as f(1, 2, 3). Does anyone know if there is a
construct in PHP to convert an array into a parameter list to achieve
the same thing?

variables passing can only be standard way

$bar=foo($1,$2, $3)

however when declaring the function you have the options of ;

function foo($first,$sec ond,$third)
{

}

or

function foo()
{
$first=func_get _arg(0);
$second=func_ge t_arg(1);
$third=func_get _arg(2);

}

or

function foo()
{
$args=func_get_ args();
$first=$args[0]; // array first element is 0
$second=$args[1];
$third=$args[2];

}

all this however does not prevent you passing array for you function to
work on ;

$bar=foo(array( 'dude','where is my','car'));

function foo($args)
{
$first=$args[0]; // array first element is 0
$second=$args[1];
$third=$args[2];
}

which what your code translated to php would do , php will pass the
array not the individual elements as separate variables

hope that helps ( sorry for the long winded explanation its better then
just saying no)

Hi, In the attached example, I do understand that the references are not changed if an array is passed by Val. What I do not understand is the result of line 99 (If one can find this by line number) which is the last line of the following sub routine: ' procedure modifies elements of array and assigns ' new reference (note ByVal) Sub FirstDouble(ByVal array As Integer()) Dim i As Integer

Using .NET 3.5, I need to pass an array of structs as parameter to a C++ unmanaged function. The C++ dll stores some data in an unmanaged cache, the function writes the values into the array of structs. The array of structs are allocated by C#. If I pass the array without 'ref' it works fine on the C++ side, but after returning to C# the array struct values are all zero. If I pass with 'ref' the application crashes. If I use a class...
