PHP实现将汉字转换为拼音及获取词语首字母的方法

　　本文实例讲述了PHP实现将汉字转换为拼音及获取词语首字母的方法。分享给大家供大家参考，具体如下：

　　最近要开发将汉字转换为拼音和得到首字的功能记录下来哈子：呵呵~

　　测试代码如下：

　　 $pinyin = new Pinyin(); echo $pinyin->getFirstChar(湖北武汉).<br/>; echo $pinyin->getPinyin(北上广).<br/>; echo $pinyin->getPinyin(火影).<br/>; echo $pinyin->getFirstChar(获得).<br/>; echo $pinyin->getFirstChar(TOM).<br/>;

　　运行结果：
