织梦获得首字母方法,并实现文章列表按首字母归类
发布时间:2020-07-11方法一,织梦默认有这个函数,在include/inc/inc_fun_funAdmin.PHP中.即SpGetPinyin()
但他只能得到全拼,没法得到首字母,
用法举例
$pingyin=GetPinyin($row['title'],0,1);
$a=substr(GetPinyin($row['title']),0,1);//得到拼音首字母
方法二,如果你只想得到首字母,不需要全拼,还可以用以下函数得到首字母
if (ord($row['title'])>128) { //汉字开头 $letter=getfirstchar2($row['title']); }else if(ord($row['title'])>=48 and ord($row['title'])<=57){ //数字开头 $letter=iconv_substr($title,0,1,'utf-8'); } else if(ord($row['title'])>=65 and ord($row['title'])<=90){ //大写英文开头 $letter=iconv_substr($row['title'],0,1,'utf-8'); }else if(ord($row['title'])>=97 and ord($row['title'])<=122){ //小写英文开头 $letter=iconv_substr($row['title'],0,1,'utf-8'); $letter=strtoupper($letter);//字母转换成大写 } print_r($letter);exit; function getfirstchar2($s0){ $s=iconv("UTF-8","gb2312", $s0); $asc=ord($s{0})*256+ord($s{1})-65536; if($asc>=-20319 and $asc<=-20284)return "A"; if($asc>=-20283 and $asc<=-19776)return "B"; if($asc>=-19775 and $asc<=-19219)return "C"; if($asc>=-19218 and $asc<=-18711)return "D"; if($asc>=-18710 and $asc<=-18527)return "E"; if($asc>=-18526 and $asc<=-18240)return "F"; if($asc>=-18239 and $asc<=-17923)return "G"; if($asc>=-17922 and $asc<=-17418)return "H"; if($asc>=-17417 and $asc<=-16475)return "J"; if($asc>=-16474 and $asc<=-16213)return "K"; if($asc>=-16212 and $asc<=-15641)return "L"; if($asc>=-15640 and $asc<=-15166)return "M"; if($asc>=-15165 and $asc<=-14923)return "N"; if($asc>=-14922 and $asc<=-14915)return "O"; if($asc>=-14914 and $asc<=-14631)return "P"; if($asc>=-14630 and $asc<=-14150)return "Q"; if($asc>=-14149 and $asc<=-14091)return "R"; if($asc>=-14090 and $asc<=-13319)return "S"; if($asc>=-13318 and $asc<=-12839)return "T"; if($asc>=-12838 and $asc<=-12557)return "W"; if($asc>=-12556 and $asc<=-11848)return "X"; if($asc>=-11847 and $asc<=-11056)return "Y"; if($asc>=-11055 and $asc<=-10247)return "Z"; return false; }三,如何实现文章列表中,按首字母进行归类归档排序?下面是完整代码
<div class="container padding-big"style="min-height:200px;"> <p>{dede:type }[field:typename/]{/dede:type}</p> <div> {dede:php} $sql = "select arc.id,arc.writer,arc.typeid, arc.title, arc.senddate,tp.sitepath,tp.namerule,tp.typedir from dede_archives arc left join `dede_arctype` tp on arc.typeid=tp.id where arc.typeid=2"; $dsql->SetQuery($sql); $dsql->Execute();//执行SQL操作 while($row = $dsql->GetArray()){ //print_r($row['title']);exit; //$pingyin=GetPinyin($row['title'],0,1); $letter=substr(GetPinyin($row['title']),0,1);//取得拼音首字母 $letter=strtoupper($letter); $arr[$letter]['writer'][]=$row["writer"]; $arr[$letter]['url'][]=GetFileUrl($row['id'],$row['typeid'],$row['senddate'],$row['title'],0,0,$row['namerule'],$row['typedir'],0, '',0,'',$row['sitepath']); $arr[$letter]['title'][]=$row["title"]; } ksort($arr);//字母排序 //print_r($arr);exit; $b=1; foreach($arr as $k=>$v){ //print_r($v);exit; echo '<div><p class="padding-left bg-eee st">'.strtoupper($k).'</p>'; for ($x=0; $x<count($v['title']); $x++) { echo '<a href="'.$v[url][$x].'"><strong>'. $v[title][$x].'</strong></a><br/><hr/>'; } echo '<br/></div>';// print_r($b%4); if($b%3==0){echo '<hr></hr>';//hr{background:#ddd;color:#ddd;clear:both;float:none;width:100%;height:1px;margin:10px 0; border:none;-moz-box-sizing:content-box;box-sizing:content-box;}hr.space{background:#fff;color:#fff;visibility:hidden;}hr的css,强制换行,防止错位 } $b++; } {/dede:php} </div> </div>
