I have a basic question here about changing array values inside a function, let’s say that I have the following array inside a class:
$my_array = array(1, 2, 3);
And then I have the following method which returns my array;
public function getAnArray()
{
return $this->my_array;
}
and then I wanna change one value of my_array (2 for example to 7) like this (based on some business logic):
public function changeArray($my_array)
{
$new_value = 7;
foreach($my_array as $key => $value){
if($value == 2){
$my_array[$key] = $new_value; // Change the value of 2 to 7
}
}
}
So that $my_array now becomes (1, 7, 3)
I understand that I have to pass something by reference for this to work, but I don’t know exactly how this should work.
