};

for ($i= 0;$i< 10;$i++) {
  $y = bind($x, $i)// how?
  $y($i);

Actual currying is maybe a bit of a stretch for PHP (;-)), nonetheless you can do stuff like this with Closures in PHP 5.3+:

function populatedList() {
    $args = func_get_args();
    return function () use ($args) {
        $localArgs = func_get_args();
        return array_merge($args, $localArgs);
    };
}

$sevenList = populatedList(7, 14, 21);

var_dump($sevenList('foo', 'bar', 'baz'));

// Array
// (
//    [0] => 7
//    [1] => 14
//    [2] => 21
//    [3] => foo
//    [4] => bar
//    [5] => baz
// )
