织梦获得首字母方法,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
$pingyin=GetPinyin($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`	`"container padding-big"style="min-height:200px;">`

`02`	`{dede:type` `}[field:typename/]{/dede:type}`

03

`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` `'` `'.strtoupper($k).'` `';`

`25`	`for` `($x=0; $xv['title']); $x++) {`

`26`	`echo` `'.$v[url][$x].'">'``. $v[title][$x].'``';`

27

28 }

`29`	`echo` `' ';// print_r($b%4);`

`30`	`if($b%3==0){echo` `' ';//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}`
