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

  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

  

  

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

  

  {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();//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 '

'.strtoupper($k).'

';

  for ($x=0; $x

  echo ''. $v[title][$x].'


';

  }

  echo '

';// print_r($b%4);

  if($b%3==0){echo '


';//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}
