帝国CMS按照26个字母顺序循环调用信息

帝国CMS按照26个字母顺序循环调用信息，也就是a/b/c/e/f/g...的顺序依次调用。

<?
$pd_record=explode(",",'A,B,C,D,E,F,G,H,J,K,L,M,N,P,Q,R,S,T,W,X,Y,Z');
for($i=0;$i<count($pd_record);$i++)
{
?>                   
<div class="letter_items">
<dt id="<?=strtolower($pd_record[$i])?>"><?=$pd_record[$i]?></dt>
<div class="letter_item_con">
<?php
$newbook=$empire->query("select id,name from {$dbtbpre}extend_linkage where zm= '".$pd_record[$i]."' and parentid<>1 and id<>1 order by id desc");
while($r=$empire->fetch($newbook)) {
$num=$empire->gettotal("select count(*) as total from {$dbtbpre}ecms_weixin where city='$r[id]'");
?>
<dd><a href="/citylist/?city=<?=$r['id']?>&t=personal"><?=str_replace('市','',esub($r['name'],10))?>(<span><?=$num?></span>)</a></dd>
<?}?>                            
</div>
</div>
<?
}
?>

主要看这段for按字母顺序循环调用的方法

<?
$pd_record=explode(",",'A,B,C,D,E,F,G,H,J,K,L,M,N,P,Q,R,S,T,W,X,Y,Z');
for($i=0;$i<count($pd_record);$i++)
{
?>

然后在看这段，内循环查询字段等于外循环字母的信息。

$newbook=$empire->query("select id,name from {$dbtbpre}extend_linkage where zm= '".$pd_record[$i]."' and parentid<>1 and id<>1 order by id desc");
