Turn array into independent function arguments - howto?

Question

I want to use values in an array as independent arguments in a function call. Example:

// Values \"a\" and \"b\"
$arr = array(\"alpha\", \"beta\");
// ... ar         


        

Answer 1

try list()

// Values "a" and "b"
$arr = array("alpha", "beta");
list($a, $b) = $arr;
my_func($a, $b);

function my_func($a,$b=NULL) { echo "{$a} - {$b}"; }
