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 class="text-large">{dede:type }[field:typename/]{/dede:type}</p>
    <div class="line-big">
    {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 `#@__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($v);exit;
    echo '<div class="x3"><p class="padding-left bg-eee st">'.strtoupper($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 class="space"></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>
