需求：每篇文章都有自己的tags,现在需要将每篇文章的keywords关键字位置调用该文章的tags标签,

<?         
$tbname=$class_r[$navinfor['classid']]['tbname'];
$ftbname=$dbtbpre."ecms_".$tbname."_data_".$navinfor['stb'];
$hlt = $empire->fetch1("select infotags from {$ftbname} where id='$navinfor[id]'");   
            $a=$hlt[infotags];
            $str=str_replace('，', ',', $a);
            $tag='';
            $t= explode(",", $str);
            
                    for($i=0;$i<count($t);$i++)
                    {
                            if($t[$i])
                            {    $datar=$empire->fetch1("select tagid from {$dbtbpre}enewstags where tagname='$t[$i]' limit 1");   
                                 $tag.=$t[$i].",";
                            }
            }
            ?>

 

调用：

 <meta name="keywords" content="<?php echo $tag; ?>"/>
