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：
='5.0') ? array_combine($_TDataKey, $_TDataValue) : _Array_Combine($_TDataKey, $_TDataValue);
arsort($_Data);
reset($_Data);
if($_Code != 'gb2312') $_String = _U2_Utf8_Gb($_String);
$_Res = '';
for($i=0; $i160) { $_Q = ord(substr($_String, ++$i, 1)); $_P = $_P*256 + $_Q - 65536; }
$_Res .= _Pinyin($_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 | $_C>>6);
$_String .= chr(0x80 | $_C & 0x3F);
}elseif($_C < 0x10000){ $_String .= chr(0xE0 | $_C>>12);
$_String .= chr(0x80 | $_C>>6 & 0x3F);
$_String .= chr(0x80 | $_C & 0x3F);
} elseif($_C < 0x200000) { $_String .= chr(0xF0 | $_C>>18);
$_String .= chr(0x80 | $_C>>12 & 0x3F);
$_String .= chr(0x80 | $_C>>6 & 0x3F);
$_String .= chr(0x80 | $_C & 0x3F);
}
return iconv('UTF-8', 'GB2312', $_String);
}
function _Array_Combine($_Arr1, $_Arr2)
{
for($i=0; $i
