Re: Get recursive array

Hi guys.. well I have a little "problem", I succeeded on retrieving a value by it's key, but I want a clean and faster method... Let me explain: I have the following function which I use to set variables in my framework like (configs, requests, etc)... /*********************************************************************** * @function_name set_vars * @function_type Method * @function_input None * @function_description None ***********************************************************************/ function set_var($key = '', $value = null) {

    if(is_array($key))
    {
        if(count($key))
        {
            foreach($key as $key_key => $key_value)
            {
                $this->vars[$key_key] = $key_value;
            }
        }
    }
    elseif(is_array($value))
    {
        if(count($value))
        {
            foreach($value as $value_key => $value_value)
            {
                $this->vars[$key][$value_key] = $value_value;
            }
        }
    }
    else
    {
        $this->vars[$key] = $value;
    }

} For example I have: $this->vars['config']['database_type'] = 'mysql'; or... $this->vars['http']['get'] = 'b'; But now I want a function that gets those values and subvalues, but there is one small catch, I need to dynamically get parsed arguments and check if key exists and returns it... I tried func_num_args, and func_get_args, without success.

I don't really have a clue as to what you want to do - but I took a guess. maybe the following is along the lines of what you are looking to do? the idea is that if you had a VarCollection object with the following: $obj->vars['a']['b']['c']['d']['e'] = 'ABCDE'; you could output the value 'ABCDE' by doing this: echo $obj->get_var('a','b','c','d','e'); the example below is not tested (mostly because I don't know what I should have tested exactly but also because I have sloth tendencies ;-) class VarCollection { var $vars; function VarCollection() { $this->vars = array(); } function set_var($key = '', $value = null) { /* bla */ } function get_var() { $args = func_get_args(); if (empty($args)) { return null; } $varRef =& $this->vars; while ($arg = array_shift($args)) { if (!isset($varRef[ $arg ])) { return null; } else { $varRef =& $varRef[ $arg ]; } } return ($xyz = $varRef); // xyz because I'm paranoid about references } }

Any ideas?
