方法一,織夢默認(rèn)有這個函數(shù),在include/inc/inc_fun_funAdmin.PHP中.即SpGetPinyin()

但他只能得到全拼,沒法得到首字母,

用法舉例

$pingyin=GetPinyin($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,還可以用以下函數(shù)得到首字母

if (ord($row['title'])>128) { //漢字開頭

$letter=getfirstchar2($row['title']);

}else if(ord($row['title'])>=48 and ord($row['title'])<=57){ //數(shù)字開頭

$letter=iconv_substr($title,0,1,'utf-8');

}

else if(ord($row['title'])>=65 and ord($row['title'])<=90){ //大寫英文開頭

$letter=iconv_substr($row['title'],0,1,'utf-8');

}else if(ord($row['title'])>=97 and ord($row['title'])<=122){ //小寫英文開頭

$letter=iconv_substr($row['title'],0,1,'utf-8');

$letter=strtoupper($letter);//字母轉(zhuǎn)換成大寫

}

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,如何實現(xiàn)文章列表中,按首字母進行歸類歸檔排序?下面是完整代碼

<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();//執(zhí)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,強制換行,防止錯位

}

$b++;

}

{/dede:php}

</div>
