你可以看看这个 - 或者使用它，解构它......

class encryption{
    private $config;

    public function __construct( $options=array() ){
        $this->config=array_merge(
            array(
                'cipher'    =>  MCRYPT_RIJNDAEL_256,
                'mode'      =>  MCRYPT_MODE_ECB,
                'key'       =>  FALSE,
                'iv'        =>  FALSE,
                'size'      =>  FALSE,
                'base64'    =>  TRUE,
                'salt'      =>  FALSE
            ),
            $options
        );
    }
    private function getivs( $config=object ){
        $config->size=mcrypt_get_iv_size( $config->cipher, $config->mode );
        $config->iv=mcrypt_create_iv( $config->size, MCRYPT_RAND );
    }
    public function encrypt( $data=NULL ){
        $config=(object)$this->config;
        $this->getivs( $config );
        $data=trim( $data );
        $module = mcrypt_module_open( $config->cipher, '', $config->mode, '' );
        mcrypt_generic_init( $module, $config->key, $config->iv );

        $output = $config->base64 ? base64_encode( mcrypt_generic( $module, $data ) ) : mcrypt_generic( $module, $data );

        mcrypt_generic_deinit( $module );
        mcrypt_module_close( $module );
        return $output;
    }
    public function decrypt( $data=NULL ){
        $config=(object)$this->config;
        $this->getivs( $config );
        mb_detect_order( 'auto' );
        $encoding=mb_detect_encoding( $data );
        if( !$data or is_null( $data ) or empty( $data ) or !$encoding or $data=='' or base64_decode( $data )=='' ) return FALSE;

        $module = mcrypt_module_open( $config->cipher, '', $config->mode, '' );
        mcrypt_generic_init( $module, $config->key, $config->iv );

        $output = $config->base64 ? rtrim( mdecrypt_generic( $module, base64_decode( $data ) ),"\0" ) : rtrim( mdecrypt_generic( $module, $data ),"\0" );

        mcrypt_generic_deinit( $module );
        mcrypt_module_close( $module );
        return urldecode( $output );
    }
}//end class

使用mycript.class.php进行PHP加密/解密
