Question

Looking at referencing in PHP is pretty much confusing me, can anyone explain to me how this would work:

private $TestArray1 = Array()
private $TestArray2 = Array()

private function test1(){
$this->test2($this->TestArray1);
$this->test2($this->TestArray2);
}

private function test2($Array){
$this->test3($Array);
}

private function test3($Array){
$Array[0] = 1;
}

Where would I be putting the “&” in this, if I wanted to have the private variables TestArray1 and TestArray2 be edited, after it is set in function test3?

Answer 1

private $TestArray1 = Array()
private $TestArray2 = Array()

private function test1(){
$this->test2($this->TestArray1);
$this->test2($this->TestArray2);
}

private function test2(&$Array){
$this->test3($Array);
}

private function test3(&$Array){
$Array[0] = 1;
}

So you need to specify & in the function declaration, and pass parameter as-is.
