汉字转拼音 繁体字 加音标的

今天分享一个可以将汉字转为拼音的 而且也可以加音标的类，

这个要感谢，那些巨人的肩膀啊

代码如下：

<?php
define('BASE_PATH', dirname(__FILE__));
class Tpinyin {
    protected $dict = array();
    protected $dictfile = 'pylib.gif';
    protected $dictoffs = 244;
    protected $tune = array();
    private $charset = '';
    private $maxlength = 0;
    private $fp;
    function __construct() {
        $this->dictfile = BASE_PATH . '/'. $this->dictfile;
        $fp = fopen($this->dictfile, 'rb');
        fread($fp, 41);
        $this->dict[] = explode(',', fread($fp, 57));
        $this->dict[] = explode(',', fread($fp, 146));
    }
    function settune() {
        $tune = array(
            'a' => array("\x01\x01","\x00\xe1","\x01\xce","\x00\xe0",),
            'e' => array("\x01\x13","\x00\xe9","\x01\x1b","\x00\xe8",),
            'i' => array("\x01\x2b","\x00\xed","\x01\xd0","\x00\xec",),
            'o' => array("\x01\x4d","\x00\xf3","\x01\xd2","\x00\xf2",),
            'u' => array("\x01\x6b","\x00\xfa","\x01\xd4","\x00\xf9",),
            'v' => array("\x01\xd6","\x01\xd8","\x01\xda","\x01\xdc",),
            );
        foreach($tune as $k=>$r)
            foreach($r as $i=>$v)
                $this->tune[$k][$i] = mb_convert_encoding($v, $this->charset, 'UCS-2');
    }
    function pinyin($str) {
        $this->charset = mb_check_encoding($str, 'UTF-8') ? 'UTF-8' : 'GBK';
    //    $this->settune();//是否加音标
        $this->fp = fopen($this->dictfile, 'rb');
        $this->maxlength = filesize($this->dictfile);
        $str = mb_convert_encoding($str, "UCS-2", "UTF-8, GBK");
        $t = array_map(array($this, 'pinyin_back'), str_split($str, 2));
        return join('', $t); //连接成串，要不要自己决定
    }
    function pinyin_back($ch) {
        if(ord($ch{0}) == 0) return $ch{1};
        $o = hexdec(bin2hex($ch)) - 0x4e00;
        if($o < 0 || $o >= $this->maxlength) return mb_convert_encoding($ch, $this->charset, 'UCS-2');
        fseek($this->fp, $o*2 + $this->dictoffs);
        $x = sprintf('%05d', current(unpack('S', fread($this->fp, 2))));
        $t = $this->dict[0][substr($x, 0, 2)+0] . $this->dict[1][substr($x, 2, 2)+0];
        $n = substr($x, -1) - 1;
        $s = $t;
        foreach($this->tune as $k=>$v) {
            $s = str_replace($k, $v[$n], $s);
            if($s != $t) break;
        }
        return "$s";//加了个空格，要不要自己决定
    }
}

这个文件是需要一个库的，但是那位大神将库放在了图片里面，我觉得很牛叉，于是就这样用了，呵呵

使用方式如下

$p = new Tpinyin;
echo $p->pinyin('惘');

结果自己试试就知道了。

如果想控制音标的话，可以考虑是不是加载这个函数settune，有加的话，就会有音标的。
