The POSIX syntax for defining functions is quicksort() <compound command>.
The ksh syntax is function quicksort <compound command>.
What you are using is a hybrid that works only in bash (and, I think perhaps in zsh).
Yes, I'm using bash. I tried the POSIX version as well, to see if it made any difference.

What do you expect in $1? Why are you using echo?
$1 should contain the array passed to the function. I found this method searching the web. Is there a better method?
I suspect the problem may be related to this since when it descends to the first recursion level, the array length is seen as 1 and the function exits, returning only three numbers from the array. A check of $l and $g just prior to passing them to the recursive call shows them as they should be, so I'm not sure what the problem is.
hi, I was wondering if there was a good way to create an array within a function, where the name is based on a passed argument? I tried this:
_____________________________
func(){
#take in 1st arg as the arrayname
arrayName=$1
let i=0
while read line
do
arrayName=${line}
let i+=1... (5 Replies)
Hi everyone, i need your input on this. We can express a function recursivly like this
A(n) = (2 n = 0
5 n = 1
A(n − 1) + A(n − 2) % 47 n > 1

forward_static_call_array
FORWARD_STATIC_CALL_ARRAY(3) 1 FORWARD_STATIC_CALL_ARRAY(3)forward_static_call_array - Call a static method and pass the arguments as arraySYNOPSIS
mixed forward_static_call_array (callable $function, array $parameters)
DESCRIPTION
Calls a user defined function or method given by the $function parameter. This function must be called within a method context, it can't
be used outside a class. It uses the late static binding. All arguments of the forwarded method are passed as values, and as an array, sim-
ilarly to call_user_func_array(3).
PARAMETERS
o $function
- The function or method to be called. This parameter may be an array, with the name of the class, and the method, or a string,
with a function name.
o $parameter
- One parameter, gathering all the method parameter in one array.
Note
Note that the parameters for forward_static_call_array(3) are not passed by reference.
RETURN VALUES
Returns the function result, or FALSE on error.
EXAMPLES
Example #1
forward_static_call_array(3) example
<?php
class A
{
const NAME = 'A';
public static function test() {
$args = func_get_args();
echo static::NAME, " ".join(',', $args)."
";
}
}
class B extends A
{
const NAME = 'B';
public static function test() {
echo self::NAME, "
";
forward_static_call_array(array('A', 'test'), array('more', 'args'));
forward_static_call_array( 'test', array('other', 'args'));
}
}
B::test('foo');
function test() {
$args = func_get_args();
echo "C ".join(',', $args)."
";
}
?>
The above example will output:
B
B more,args
C other,args
