##lexer & parser

lexer

Array ( [0] => <p> [1] => p_start [2] => <block> [3] => block_info [4] => <b> [5] => bold> [6] => </b> [7] => </block> [8] => <block> [9] => info2 [10] => </block> [11] => p_end [12] => </p> )

render

In the mean time, to adjusting the undefined attributes to the given class, I use the __call method to solve this.

  public function __call($name, array $params){
        if (!empty($params[1]) || !empty($params[0])) {
            $this->attribute[$name] = $params[0];
        }
        return $this;
    }

following is the test case to generate a given image.

$img = new TagGenerator('img');
$img->src('../img/bold.png')->alt('Example image');
echo (string) $img;
