I have a PHP function that can take a variable number of arguments (and I use func_get_args() to process them)

class Test {

    private $ting = FALSE;

    public function test() {
        $args = func_get_args();
        if ($this->ting) {
            var_dump($args);
        } else {
            $this->ting = TRUE;
            $this->test($args); //I want to call the function again using the same arguments. (this is pseudo-code)
        }
    }

}

This function is not recursive (the "$ting" variable prevents it from going more than once).

I want test() to call itself using the same arguments it was given. So for example: Test->test("a", "b", "c"); would output the following:

array(3) { [0]=> string(1) "a" [1]=> string(1) "b" [2]=> string(1) "c" }

I think you want to use call_user_func_array(); it takes a callable and an array of arguments.

call_user_func_array(array($this, 'test'), $args);

And then calls the function like:

test($args[0], $args[1], ...)

The first parameter is a reference to an object method in the shape of an array of two elements; the first being the object, the second a method name.

Btw, this won't work for private methods because the call context of call_user_func_array() is outside of your object.

Use call_user_func_array.

Example:

class TestClass {

    private $ting = FALSE;

    public function test() {
        $args = func_get_args();
        if ($this->ting) {
            var_dump($args);
        } else {
            $this->ting = TRUE;
            call_user_func_array(array($this, 'test'),$args);
        }
    }

}

$test = new TestClass();

//Outputs array(3) { [0]=> string(6) "apples" [1]=> string(7) "oranges" [2]=> string(5) "pears" }
$test->test("apples","oranges","pears");

why &$this rather than just $this? –  DrAgonmoray Jul 11 '13 at 23:36
    
Personal preference. Either way will work. –  maxton Jul 11 '13 at 23:39

while($this -> ting == TRUE){
$this -> test($args);
}
