两句php语句怎么整合
第一句：
//添加内链
$innerlink = $this->model('innerlink')->all_innerlink();
if($innerlink){
$last_id = $this->model('innerlink')->get_last_link_id();
for($i=0;$i<$last_id;$i++)
{
$title[$i] = $innerlink[$i]['title'];
$link[$i] = '<a href='.$innerlink[$i]['description'].' target="_blank">'.$innerlink[$i]['title'].'</a>';
$article_info['message'] = $this->model('innerlink')->str_replace_once($title[$i],$link[$i],$article_info['message']);
}
//$res = $this->model('innerlink')->str_replace_once($title,$link,$article_info['message']);
//$article_info['message'] = $res;
}
//内链添加结束
第二句：
$content = $article_info['message'];
$res = $this->model('innerlink')->get_category_topic_list(1);
//print_r($res);
foreach($res AS $r) {
$id = $r['id'];
$title = $r['title'];
if($r['t']=='c'){
$content = str_replace($title,"<a href=\"/explore/category-$id\" >$title</a>",$content);
}else{
$content = str_replace($title,"<a href=\"/topic/$title\" >$title</a>",$content);
}
}
$article_info['message'] = $content;
SQL如下：
public function get_category_topic_list($type=2)
{
$result_cache_key = 'get_category_tag_list'.$type;
// AWS_APP::cache()->delete($result_cache_key);
if ($result = AWS_APP::cache()->get($result_cache_key)){
return $result;
}
switch($type){
case 1:
$sql = "SELECT `id` ,`title`,'c' as t FROM ".get_table('category');
break;
case 2:
$sql = " SELECT `topic_id` id ,`topic_title` title,`url_token` url_token,'t' as t FROM ".get_table('topic');
break;
default:
$sql = "SELECT `id` ,`title`,'c' as t FROM ".get_table('category')." union SELECT `topic_id` id ,`topic_title` title,`url_token` url_token,'t' as t FROM ".get_table('topic');
}
if ($result = $this->query_all($sql))
{
$filter = array('href','ref','ef','f');
$i=0;
foreach($result as $r) {
if(in_array($r['title'],$filter))continue;
$resulta[$r['title']]['id'] = $r['id'];
$resulta[$r['title']]['title'] = $r['title'];
$resulta[$r['title']]['t'] = $r['t'];
$resulta[$r['url_token']]['url_token'] = $r['url_token'];
}
AWS_APP::cache()->set($result_cache_key, $resulta, get_setting('cache_level_high'));
return $resulta;
}else{
return null;
}
}
说明，第一句是通过后台设置关键词，有就自动添加后台的链接，第二句是通过topic来查询，如果存在topic就内链到topic两个代码有冲突，新手不会整合，求带！把他们整合起来，就是如果有后台关键词就链接，有topic就链接
