代码如下（示例）：

class FragmentTag extends TagLib
{

    protected $tags = array(
		'sql'    	 => ['attr' => 'query,connect', 'alias' => 'iterate'],
		'relate'     => ['attr' => 'sqlstr','level'=>3],
		'newslist'=>['attr'=>'classid,field,order,num,sqlstr,flag,group,result,empty,cache,extend','level'=>3],
		'list'=>['attr'=>'table,classid,field,num,order,sqlstr,cache','level'=>3],
		'query'=>['attr'=>'table,field,num,order,sqlstr,cache','level'=>3],
		'class'=>['attr'=>'field,num,order,sqlstr,cache','level'=>3],
		'page'=>['attr'=>'table,field,num,order,sqlstr,cache','level'=>1],
		'sig'  => ['attr'=>'id,field,cache','close'=>0],
		'input' => ['attr' => 'id,name,hidden,readonly,onclick,style','close' => 0],
    );

	public function tagSql($tag, $content)
    {   
        $result= !empty($tag['result'])?$tag['result']: 'sql';
		preg_match_all('/select(.*)from/iUs',$tag['query'],$all);
		if(!empty($all[1][0])){
			$sqlvalue = explode(',',trim($all[1][0]));
		}
		$connect.=($tag['connect'])?$tag['connect']:config('database.default');
		$tag['query'] = str_replace('pre_',config('database.connections.'.$connect.'.prefix'),$tag['query']);
		if(false == strpos($tag['query'],'.')){
			$tag['query'] = str_replace('\'','"',$tag['query']);
		}
        $data ="\\think\\facade\\Db::connect('".$connect."')->query('{$tag['query']}')";
