导读：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

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 01 if (ord($row['title'])>128) { //汉字开头 02 $letter=getfirstchar2($row['title']); 03 }else if(ord($row['title'])>=48 and ord($row['title'])<=57){ //数字开头 04 $letter=iconv_substr($title,0,1,'utf-8'); 05 } 06 else if(ord($row['title'])>=65 and ord($row['title'])<=90){ //大写英文开头 07 $letter=iconv_substr($row['title'],0,1,'utf-8'); 08 }else if(ord($row['title'])>=97 and ord($row['title'])<=122){ //小写英文开头 09 $letter=iconv_substr($row['title'],0,1,'utf-8'); 10 $letter=strtoupper($letter);//字母转换成大写 11 } 12 print_r($letter);exit; 13 function getfirstchar2($s0){ 14 $s=iconv("UTF-8","gb2312", $s0); 15 $asc=ord($s{0})*256+ord($s{1})-65536; 16 if($asc>=-20319 and $asc<=-20284)return "A"; 17 if($asc>=-20283 and $asc<=-19776)return "B"; 18 if($asc>=-19775 and $asc<=-19219)return "C"; 19 if($asc>=-19218 and $asc<=-18711)return "D"; 20 if($asc>=-18710 and $asc<=-18527)return "E"; 21 if($asc>=-18526 and $asc<=-18240)return "F"; 22 if($asc>=-18239 and $asc<=-17923)return "G"; 23 if($asc>=-17922 and $asc<=-17418)return "H"; 24 if($asc>=-17417 and $asc<=-16475)return "J"; 25 if($asc>=-16474 and $asc<=-16213)return "K"; 26 if($asc>=-16212 and $asc<=-15641)return "L"; 27 if($asc>=-15640 and $asc<=-15166)return "M"; 28 if($asc>=-15165 and $asc<=-14923)return "N"; 29 if($asc>=-14922 and $asc<=-14915)return "O"; 30 if($asc>=-14914 and $asc<=-14631)return "P"; 31 if($asc>=-14630 and $asc<=-14150)return "Q"; 32 if($asc>=-14149 and $asc<=-14091)return "R"; 33 if($asc>=-14090 and $asc<=-13319)return "S"; 34 if($asc>=-13318 and $asc<=-12839)return "T"; 35 if($asc>=-12838 and $asc<=-12557)return "W"; 36 if($asc>=-12556 and $asc<=-11848)return "X"; 37 if($asc>=-11847 and $asc<=-11056)return "Y"; 38 if($asc>=-11055 and $asc<=-10247)return "Z"; 39 return false; 40 } 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 01 <div class="container padding-big"style="min-height:200px;"> 02 <p>{dede:type }[field:typename/]{/dede:type}</p> 03 <div> 04 {dede:php} 05 $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"; 06 $dsql->SetQuery($sql); 07 $dsql->Execute();//执行SQL操作 08 while($row = $dsql->GetArray()){ 09 //print_r($row['title']);exit; 10 //$pingyin=GetPinyin($row['title'],0,1); 11 $letter=substr(GetPinyin($row['title']),0,1);//取得拼音首字母 12 $letter=strtoupper($letter); 13 14 $arr[$letter]['writer'][]=$row["writer"]; 15 $arr[$letter]['url'][]=GetFileUrl($row['id'],$row['typeid'],$row['senddate'],$row['title'],0,0,$row['namerule'],$row ['typedir'],0, '',0,'',$row['sitepath']); 16 $arr[$letter]['title'][]=$row["title"]; 17 } 18 ksort($arr);//字母排序 19 //print_r($arr);exit; 20 $b=1; 21 foreach($arr as $k=>$v){ 22 23 //print_r($v);exit; 24 echo '<div><p class="padding-left bg-eee st">'.strtoupper($k).'</p>'; 25 for ($x=0; $x<count($v['title']); $x++) { 26 echo '<a href="'.$v[url][$x].'"><strong>'. $v[title][$x].'</strong></a><br/><hr/>'; 27 28 } 29 echo '<br/></div>';// print_r($b%4); 30 if($b%3==0){echo '<hr></hr>';//hr{background:#ddd;color:#ddd;clear:both;float:none;width:100%;height:1px; margin:10px 0; 31 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 32 } 33 $b++; 34 } 35 {/dede:php} 36 </div> 37 </div> （编辑：鞍山站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
