dedecms织梦获得首字母或拼音的方法,并实现文章列表按首字母归类

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

1$pingyin=GetPinyin($row['title'],0,1); 
2$a=substr(GetPinyin($row['title']),0,1);//得到拼音首字母 <a class="ViewSource" href="http://blog.csdn.net/viqecel/article/details/50087975#" style="font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_plain.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;" title="view plain">view plai</a><span class="tracking-ad" data-mod="popu_168" style="color: silver; font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; margin: 0px; padding: 0px;"> <a class="CopyToClipboard" href="http://blog.csdn.net/viqecel/article/details/50087975#" style="box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; font-size: 9px; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_copy.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;" title="copy">copy</a></span>

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

01if(ord($row['title'])>128) { //汉字开头 
02
03$letter=getfirstchar2($row['title']); 
04
05}elseif(ord($row['title'])>=48 andord($row['title'])<=57){ //数字开头 
06
07$letter=iconv_substr($title,0,1,'utf-8'); 
08
09}elseif(ord($row['title'])>=65 andord($row['title'])<=90){ //大写英文开头 
10
11$letter=iconv_substr($row['title'],0,1,'utf-8'); 
12
13
14}elseif(ord($row['title'])>=97 andord($row['title'])<=122){ //小写英文开头 
15
16$letter=iconv_substr($row['title'],0,1,'utf-8'); 
17$letter=strtoupper($letter);//字母转换成大写 
18} 
19
20print_r($letter);exit; 
21functiongetfirstchar2($s0){ 
22$s=iconv("UTF-8","gb2312", $s0);  
23$asc=ord($s{0})*256+ord($s{1})-65536;  
24if($asc>=-20319 and$asc<=-20284)return"A";  
25if($asc>=-20283 and$asc<=-19776)return"B";  
26if($asc>=-19775 and$asc<=-19219)return"C";  
27if($asc>=-19218 and$asc<=-18711)return"D";  
28if($asc>=-18710 and$asc<=-18527)return"E";  
29if($asc>=-18526 and$asc<=-18240)return"F";  
30if($asc>=-18239 and$asc<=-17923)return"G";  
31if($asc>=-17922 and$asc<=-17418)return"H";  
32if($asc>=-17417 and$asc<=-16475)return"J";  
33if($asc>=-16474 and$asc<=-16213)return"K";  
34if($asc>=-16212 and$asc<=-15641)return"L";  
35if($asc>=-15640 and$asc<=-15166)return"M";  
36if($asc>=-15165 and$asc<=-14923)return"N";  
37if($asc>=-14922 and$asc<=-14915)return"O";  
38if($asc>=-14914 and$asc<=-14631)return"P";  
39if($asc>=-14630 and$asc<=-14150)return"Q";  
40if($asc>=-14149 and$asc<=-14091)return"R";  
41if($asc>=-14090 and$asc<=-13319)return"S";  
42if($asc>=-13318 and$asc<=-12839)return"T";

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 class="text-large">{dede:type }[field:typename/]{/dede:type}</p> 
03<div class="line-big"> 
04{dede:php}  
05$sql= "select arc.id,arc.writer,arc.typeid, arc.title, arc.senddate,tp.sitepath,tp.namerule,tp.typedir from dede_archives  arc  left join `arctype` tp on arc.typeid=tp.id where arc.typeid=2"; 
06$dsql->SetQuery($sql); 
07$dsql->Execute();//执行SQL操作 
08while($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'][]=$row["title"];        
17}  
18ksort($arr);//字母排序 
19//print_r($arr);exit; 
20$b=1; 
21foreach($arras$k=>$v){ 
22
23//print_r($v);exit; 
24echo'<div class="x3"><p class="padding-left bg-eee st">'.strtoupper($k).'</p>'; 
25for($x=0; $x<count($v['title']); $x++) { 
26echo'<a href="'.$v[url][$x].'"><strong>'. $v[title][$x].'</strong></a><br/><hr/>'; 
27
28}     
29echo'<br/></div>';// print_r($b%4); 
30if($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 
31} 
32$b++; 
33} 
34{/dede:php} 
35</div> 
36</div><a class="ViewSource"href="http://blog.csdn.net/viqecel/article/details/50087975#"style="font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_plain.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;"title="view plain">view plain</a><span class="tracking-ad"data-mod="popu_168"style="color: silver; font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: 9px; box-sizing: border-box; margin: 0px; padding: 0px;"> <a class="CopyToClipboard"href="http://blog.csdn.net/viqecel/article/details/50087975#"style="box-sizing: border-box; color: rgb(202, 12, 22); text-decoration: none; margin: 0px 10px 0px 0px; padding: 1px; outline: none; border: none; font-size: 9px; display: inline-block; width: 16px; height: 16px; text-indent: -2000px; background-image: url("images/default/ico_copy.gif"); background-attachment: initial; background-color: inherit; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0% 0%; background-repeat: no-repeat;"title="copy">copy</a></span>
