Passing a array to a function, a basic feature in modern language, seems to be only possible in KSH. Not in BASH. Depite all my efforts I couldn't come to a solution. See the following examples:
It works perfectly in KSH:

Hi,
I'm trying to write a function that reassigns an array to
another local array but the method used in reassigning
the array reformats the contents of the array which is
what I am trying to prevent.
The method used to load a file into an array works as
expected and the entire array is... (4 Replies)

It also appears that awk scripts... (3 Replies)

FUNC_GET_ARGS(3) 1 FUNC_GET_ARGS(3)func_get_args - Returns an array comprising a function's argument listSYNOPSIS
array func_get_args (void )
DESCRIPTION
Gets an array of the function's argument list.
This function may be used in conjunction with func_get_arg(3) and func_num_args(3) to allow user-defined functions to accept variable-
length argument lists.
RETURN VALUES
Returns an array in which each element is a copy of the corresponding member of the current user-defined function's argument list.

| 5.3.0 | |

| | This function can now be used in parameter |
| | lists. |

| 5.3.0 | |
| | |
| | If this function is called from the outermost |
| | scope of a file which has been included by call- |
| | ing include(3) or require(3) from within a func- |
| | tion in the calling file, it now generates a |
| | warning and returns FALSE. |
| | |
+--------+---------------------------------------------------+
ERRORS /EXCEPTIONS
Generates a warning if called from outside of a user-defined function.
EXAMPLES
Example #1
func_get_args(3) example
<?php
function foo()
{
$numargs = func_num_args();
echo "Number of arguments: $numargs
";
if ($numargs >= 2) {
echo "Second argument is: " . func_get_arg(1) . "
";
}
$arg_list = func_get_args();
for ($i = 0; $i < $numargs; $i++) {
echo "Argument $i is: " . $arg_list[$i] . "
";
}
}
foo(1, 2, 3);
?>
The above example will output:
Number of arguments: 3
Second argument is: 2
Argument 0 is: 1
Argument 1 is: 2
Argument 2 is: 3
Example #2
func_get_args(3) example before and after PHP 5.3
test.php
<?php
function foo() {
include './fga.inc';
}
foo('First arg', 'Second arg');
?>
fga.inc
<?php
$args = func_get_args();
var_export($args);
?>
Output previous to PHP 5.3:
array (
0 => 'First arg',
1 => 'Second arg',
)
Output in PHP 5.3 and later:
Warning: func_get_args(): Called from the global scope - no function
context in /home/torben/Desktop/code/ml/fga.inc on line 3
false
Example #3
func_get_args(3) example of byref and byval arguments
<?php
function byVal($arg) {
echo 'As passed : ', var_export(func_get_args()), PHP_EOL;
$arg = 'baz';
echo 'After change : ', var_export(func_get_args()), PHP_EOL;
}
function byRef(&$arg) {
echo 'As passed : ', var_export(func_get_args()), PHP_EOL;
$arg = 'baz';
echo 'After change : ', var_export(func_get_args()), PHP_EOL;
}
$arg = 'bar';
byVal($arg);
byRef($arg);
?>
The above example will output:
0 => 'bar', ) After change : array (
0 => 'bar', ) As passed : array (
0 => 'bar', ) After change : array (
0 => 'baz', )
NOTES
Note
Because this function depends on the current scope to determine parameter details, it cannot be used as a function parameter in ver-
sions prior to 5.3.0. If this value must be passed, the results should be assigned to a variable, and that variable should be
passed.
Note
If the arguments are passed by reference, any changes to the arguments will be reflected in the values returned by this function.
Note
This function returns a copy of the passed arguments only, and does not account for default (non-passed) arguments.
