hi,

es ist ja eigentlich ein shuffler, oder? der memorized, und zwar serialisiert. also eigentlich ein SerializedShuffleMemorizer.

  
<?php  
/**  
* Saves List in serialized File an picks new Item every call until End, then shuffles new.  
*/  
class MemorizedShuffle  
{  
    private $_serFileName = "";  
    private $_toShuffle = "";  
    private $_shuffled = array();  
    private $_nextItem = "";  
    /**  
     * Constructor  
     *@param string filename, array List to Shuffle  
     * @return void  
     */  
    public function __construct($serFileName, $toShuffle) {  
    $this->_serFileName = $serFileName;  
        $this->_toShuffle = $toShuffle;  
        if(!file_exists($this->_serFileName)) {  
            $this->_createNewShuffledFile();  
        }  
        $this->_read();  
    }  
    private function _createNewShuffledFile() {  
        $this->_shuffled = $this->_toShuffle;  
        shuffle($this->_shuffled);  
        $this->_write();  
    }  
    private function _write() {  
        if (false === file_put_contents($this->_serFileName, serialize($this->_shuffled))) {  
        throw new Exception ("Could not write");  
    };  
    }  
    private function _read() {  
        $this->_shuffled = unserialize(file_get_contents($this->_serFileName));  
    if (false === $this->_shuffled) {  
        throw new Exception ("Could not read");  
    }  
    }  
    public function getNext() {  
        //~ var_dump($this->_shuffled);  
        if (count($this->_shuffled) === 0) {  
            $this->_createNewShuffledFile();  
        }  
        $actualItem = array_shift($this->_shuffled);

        return $actualItem;

};  
$myShuffler = new MemorizedShuffle("ColorsShuffled.ser", array("blau", "rot", "grün", "schwarz"));  
var_dump($myShuffler->getNext());
