怎么在function里操作pdo呀

如何在function里操作pdo呀
代码如下
require("../inc/pdo.php");

function output($action,$select,$name){
$select=$dbc->prepare("select id,ztname,zttype,zttime,headimg,riseimg from naszt where 1=1 and zttype=:zttype");
$select->bindValue(":zttype",$action);
$select->execute();
$result='';
while($row=$select->fetch()){
$result.='
  • ';
    $result.='';
    $result.='';
    $result.='
      ';
      $result.='
    • 测试1
    • ';
      $result.='
    • 测试12
    ';
    $result.='

    '.$row['ztname'].'

    ';
    $result.=''. $row['zttype'].'';
    $result.='

    1推荐日期:'.$row['zttime'].'

  • ';
    }
    return $result;
    }



header("Content-Type:text/html;charset=utf-8");
$dbtype='mysql';
$host='127.0.0.1';
$dbName='nas';
$user='227227';
$pass='227227';
$db="$dbtype:host=$host;dbname=$dbName";
try{
$dbc=new PDO($db,$user,$pass);
$dbc->exec('SET CHARACTER SET utf8');
$dbc->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); //禁用prepared statements的仿真
}catch(PDOException $e){
echo $e->getMessage();
}
?>


我想在function调用pdo
是不是在pdo里面写class function要继承这个类?

求大神出手指点该如何写!

推荐看一下这个呀  
http://php.xlxz.org/2013/11/370/


 
include 'sql_build_query.php';
include 'pdo_query.php';
$db = new pdo_db;

$sql = $db->pdo_query('show databases ');

var_dump( $sql, $db->dbVersion() );

exit;

$sql = $db->select( 'i.kd k, io.id dk, iil.ii ds' )->from( 'test t' )
->leftjoin( 'post p', 't.id = ?', array( 2 ) )
->order( 'name DESC, id ASC' )
->where( array( 'xin = ? AND do > ?' => array( 1,3 )))
->having( array('xin' => 'dkls' ))
->group( 'id' )
->limit( 3,4 )
->queryAll();
exit;
//var_dump( $sql );

$sql = $db->from( 'test')
->insert( array( 'kd' => '233', 'dkwe' => 323 ));

$sql = $db->from( 'test' )
->where( array( '( dk = ? and kd > ?) or ( dk = ? and ddd = ?)' => array( 2,3,5,4 )))
->limit( 2 , 4 )
->update( array( 'dkddl' => 'd', 'kdls' => 'dkdl' ));

$sql = $db->from( 'test,test' )
->select( 'test,test' )
->where( array( 'id' => array( 3,3,4,2,3) ))
->limit( '3', 3)
->delete();

包含pdo类文件,实例化类,给参数。

好的,另外我想请问下您,pdo如何拼接sql呀 比如where 1=1 and tile=null 没有值就忽略掉


WHere后面随便拼 一个变量 需要的时候赋值就是了
