PHP中文转拼音及提取首字母

话不多说，直接上代码！

方法一：某些中文转化不了， 如锂等

function getFirstCharter($str)

{

$str= iconv("UTF-8","gb2312", $str);//如果程序是gbk的，此行就要注释掉

if (preg_match("/^[\x7f-\xff]/", $str))

{

$fchar=ord($str{0});

if($fchar>=ord("A") and $fchar<=ord("z") )return strtoupper($str{0});

$a = $str;

 

$val=ord($a{0})*256+ord($a{1})-65536;

//print_r($val);die;

if($val>=-20319 and $val<=-20284)return "A";

if($val>=-20283 and $val<=-19776)return "B";

if($val>=-19775 and $val<=-19219)return "C";

if($val>=-19218 and $val<=-18711)return "D";

if($val>=-18710 and $val<=-18527)return "E";

if($val>=-18526 and $val<=-18240)return "F";

if($val>=-18239 and $val<=-17923)return "G";

if($val>=-17922 and $val<=-17418)return "H";

if($val>=-17417 and $val<=-16475)return "J";

if($val>=-16474 and $val<=-16213)return "K";

if($val>=-16212 and $val<=-15641)return "L";

if($val>=-15640 and $val<=-15166)return "M";

if($val>=-15165 and $val<=-14923)return "N";

if($val>=-14922 and $val<=-14915)return "O";

if($val>=-14914 and $val<=-14631)return "P";

if($val>=-14630 and $val<=-14150)return "Q";

if($val>=-14149 and $val<=-14091)return "R";

if($val>=-14090 and $val<=-13319)return "S";

if($val>=-13318 and $val<=-12839)return "T";

if($val>=-12838 and $val<=-12557)return "W";

if($val>=-12556 and $val<=-11848)return "X";

if($val>=-11847 and $val<=-11056)return "Y";

if($val>=-11055 and $val<=-10247)return "Z";

}

else

{

return false;

}

}

方法二：利用QQ字体转化

function GetPinyin($str,$charset="utf-8",$ishead = 0) { $restr = ''; $str = trim($str); if ($charset == "utf-8") { $str = iconv("UTF-8", "GB18030", $str); } //echo $str;die; $slen = strlen($str); $pinyins = array(); if ($slen < 2) { return $str; } $fp = fopen('./test/pinyin.dat', 'r'); //设置字库路径 while (!feof($fp)) { $line = trim(fgets($fp)); $pinyins[$line[0] . $line[1]] = substr($line, 3, strlen($line) - 3); } fclose($fp); for ($i = 0; $i < $slen; $i++) { if (ord($str[$i]) > 0x80) { $c = $str[$i] . $str[$i + 1]; $i++; if (isset($pinyins[$c])) { if ($ishead == 0) { $restr .= $pinyins[$c]; } else { $restr .= $pinyins[$c][0]; } } else { $restr .= "_"; } } else if (preg_match("/[a-z0-9]/i", $str[$i])) { $restr .= $str[$i]; } else { $restr .= "_"; } } return $restr; }
