帝国cms内容页获取分割字段值并且查询匹配其他表字段值输出结果

<?php
$cizu1 = $navinfor[cizu];
$fzuci = explode(',', $cizu1);
$ffzuci = count($fzuci);
$zc = '';
$count = 0; 
for ($i = 0; $i < $ffzuci; $i++) {
    $rr = $empire->fetch1("SELECT id, classid, duyin, title, titleurl FROM {$dbtbpre}ecms_zidian WHERE title='$fzuci[$i]' and duyin !='' LIMIT 10");
    if ($rr['id']) {
        $zc .= '<a href="'.$rr['titleurl'].'" rel="external nofollow" >'.$rr['title'].'</a>';

        $count++; 
    }
    if ($count >= 6) {
        break; 
    }
}
echo $zc;
?>

用逗号分割cizu字段，并且将分割开的每一个值都与{$dbtbpre}ecms_zidian中的title值匹配
