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";
