别不多说，直接上代码
template.php（3.55K）

class template {

  protected $data = array();

  protected $drillmode = 0;

  function __construct($s) {

	if(file_exists($s)) $s = file_get_contents($s);

	$this->data = explode('<', $s);

	$this->data[0] = '';

	$this->find_dsn();

  }

  //新增 run 方法，

  function run() {

	//include "data://," . join('<', $this->data);

	eval('?>' . join('<', $this->data));

  }

  function find($pattern) {

	$this->pattern = $pattern;

	return array_filter($this->data, array($this, 'find_callback'));

  }

  private function find_dsn() {

	foreach($this->find("#\bdsn\b#i") as $k=>$v) {

		$t = $this->find_tag($tag = strtok($v, ' '), $k);

		end($t);

	}

	if($this->drillmode) {

			unset($dsn[$t]);

		}

	}

	foreach($dsn as $v) {

		list($start, $end) = $v;

		preg_match('/\bdsn\s*=\s*([^\s>]+)/i', $this->data[$start], $reg);
