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.='<ul id="thumbs"><li class="'.$name.'">';$result.='<div class="img-container">';$result.='<div class="item-img">';$result.='<img  src="ztImg/'.$row['riseimg'].'"   style="max-width:90%"如何在function里操作pdo呀" ></div><ul>';$result.='<li><a href="portfolio-single.html" class="view">测试1</a></li>';$result.='<li><a href='.$row['headimg'].' class="preview" data-rel="prettyPhoto[web]">测试12</a></li></ul></div><div class="item-info">';$result.='<h3 class="title">'.$row['ztname'].'</h3>';$result.='<span class="category">'. $row['zttype'].'</span>';	$result.='<p class="intro">1推荐日期:'.$row['zttime'].'</p></div></li>';	}return $result;}


<?phpheader("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!


回复讨论(解决方案)

如果不用global的基础上

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

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

<?php 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();

WHere后面随便拼 一个变量 需要的时候赋值就是了

根据需要
$where=" WHERE xxxx=xxx";
否则
$where="";


$SQL="SELECT * FROM XXX $where";
