PHP无限级分类的展示问题。折腾一天了,搞不定呀
函数:

<br />//无限分类显示函数<br />function get_str($id = 0) { <br />    global $str; <br />    $sql = "select classid,classname,classstate,classtype,classurl,classpage,classorder,classtitle,classkeyword,classdescription,classpid from bz_class where classpid= $id";  <br />    $result = mysql_query($sql);//查询pid的子类的分类 <br />    if($result && mysql_affected_rows()){//如果有子类 <br />        while ($row = mysql_fetch_array($result)) { //循环记录集<br />		 	$str.= "<tr><td>" .$row['classid']. "</td><td>". $row['classname']. "<p>ID: 882233</p></td><td>". $row['classtype']."</td><td>". $row['classid']."</td><td>". $row['classid']."</td><td>". $row['classid']."</td></tr>" ; //字符串构建<br />            get_str($row['classid']); //调用get_str(),将记录集中的id参数传入函数中,继续查询下级 <br />        } <br />    } <br />    return $str; <br />} <br />



求高手赐教。

<br />//无限分类显示函数<br />function get_str($id = 0, $depth=0) { <br />    global $str; <br />    $sql = "select classid,classname,classstate,classtype,classurl,classpage,classorder,classtitle,classkeyword,classdescription,classpid from bz_class where classpid= $id";  <br />    $result = mysql_query($sql);//查询pid的子类的分类 <br />    if($result && mysql_affected_rows()){//如果有子类 <br />        while ($row = mysql_fetch_array($result)) { //循环记录集<br />            $str.= "<tr><td>" .$row['classid']. "</td><td>".str_repeat ( "└" ,$depth). $row['classname']. "<p>ID: 882233</p></td><td>". $row['classtype']."</td><td>". $row['classid']."</td><td>". $row['classid']."</td><td>". $row['classid']."</td></tr>" ; //字符串构建<br />            get_str($row['classid'], $depth+1); //调用get_str(),将记录集中的id参数传入函数中,继续查询下级 <br />        } <br />    } <br />    return $str; <br />}<br />
