Question

Here is an example of my class, I have default options defined in the constructor and I want to replace them with any options provided.

class Class{
  private $options;

  function __construct($options=null){
    $this->options = array('option1'=>'value', 'option2'=>'value', ...);
    array_replace(_recursive)($this->options,$options);
  }

  function showOpts(){
    print_r($this->options);
  }
}

$opt = array('newOpt'=>value ..);
$c = new Class($opt);
$c->showOpts();

when I print the contents of options I get the default values without any replacement.
What am I doing wrong?

Answer 1

Because array_replace_recursive returns the resulting array.

You should assign its result to $this->options
