简介网络上类似的代码大多只能在gb2312编码下使用，下面这个类同时能在utf-8编码下将汉字转换为拼音。具体的代码和用法如下：复制代码 代码如下:$_Res .= _Pinyin($_P, $_Data);
}
return preg_replace("/[^a-z0-9]*/", '', $_Res);
}
function _Pinyin($_Num, $_Data)
{
if ($_Num>0 && $_Num<160 ) return chr($_Num);
elseif($_Num<-20319 || $_Num>-10247) return '';
else {
foreach($_Data as $k=>$v){ if($v<=$_Num) break; }
return $k;
}
}
function _U2_Utf8_Gb($_C)
{
$_String = '';
if($_C < 0x80) $_String .= $_C;
elseif($_C < 0x800)
{
$_String .= chr(0xC0 | $_C6);
$_String .= chr(0x80 | $_C & 0x3F);
}elseif($_C < 0x10000){
$_String .= chr(0xE0 | $_C12);
$_String .= chr(0x80 | $_C6 & 0x3F);
$_String .= chr(0x80 | $_C & 0x3F);
} elseif($_C < 0x200000) {
$_String .= chr(0xF0 | $_C18);
$_String .= chr(0x80 | $_C12 & 0x3F);
$_String .= chr(0x80 | $_C6 & 0x3F);
$_String .= chr(0x80 | $_C & 0x3F);
}
return iconv('UTF-8', 'GB2312', $_String);
}
function _Array_Combine($_Arr1, $_Arr2)
{
for($i=0; $i<count($_Arr1); $i++) $_Res[$_Arr1[$i]] = $_Arr2[$i];
return $_Res;
}
//用法：
//第二个参数留空则为gb1232编码
echo Pinyin('');
//第二个参数随意设置则为utf-8编码
echo Pinyin('张三',1);
?>
