1、PHP实现汉字转拼音类_ PHP实现汉字转拼音类,GB2312标准共收录6763个汉字，不在范围内的汉字是无法转换，如：中国前总理_的“镕”字。 GB2312中对所收汉字进行了“分区”处理，每区含有94个汉字符号。这种表示方式也称为区位码。 01-09区为特别符号。 16-55区为一级汉字，按拼音排序。（3755个） 56-87区为二级汉字，按部首笔画排序。（3008个） 10-15区及88-94区则未有编码。 占用的码位是72*94=6768。其中有5个空位是D7FA-D7FE。所以实际共6763个汉字。其中一级汉字3755个，二级汉字3008个。而此类算法实际只能转换3755个汉字。 优点
2、：没有用法大文字库，文件相对较小，没有用法正则表达式，性能相对较高。支持首字母转换。 缺点：只能转换3755个汉字，多音字无法识别。 具体代码如下： ?php / 此类是依据ASCII码转换，GB2312库对多音字也无能为力，此类优点是性能比较高。 / GB2312标准共收录6763个汉字，此类的算法只支持其中的一级汉字3755个，不在范围内的汉字是无法转换，如：中国前总理_的“镕”字。 class pinyin public static function utf8_to($s, $isfirst = false) return self:to(self:utf8_to_gb2312($s)
