Array zufällig ausgeben und ausgegeben Werte merken - so?

hi,

  
<?php  
class Colors  
{  
    private $_serFileName = "myColorsShuffled.ser";  
    private $_colors = array("blau", "rot", "grün", "schwarz");  
    private $_colorsShuffled = array();  
    private $_nextColor = "";  
    public function __construct() {  
        if(!file_exists($this->_serFileName)) {  
            $this->_createNewShuffledFile();  
        }  
        $this->_read();  
    }  
    private function _createNewShuffledFile() {  
        $this->_colorsShuffled = $this->_colors;  
        shuffle($this->_colorsShuffled);  
        $this->_write();  
    }  
    private function _write() {  
        file_put_contents($this->_serFileName, serialize($this->_colorsShuffled));  
    }  
    private function _read() {  
        $this->_colorsShuffled = unserialize(file_get_contents($this->_serFileName));  
    }  
    public function getNext() {  
        //~ var_dump($this->_colorsShuffled);  
        if (count($this->_colorsShuffled) === 0) {  
            $this->_createNewShuffledFile();  
        }  
        $actualColor = array_shift($this->_colorsShuffled);  
        $this->_write();  
        return $actualColor;  
    }  
};  
$myColors = new Colors();  
echo $myColors->getNext();  

Sollte "funzen". ggfs. mal das Var_dump() wieder einkommentieren ...;

mfg
