PHP汉字转拼音的两种步骤+PHP提取汉字(中文)方法

PHP汉字转拼音的两种方法+PHP提取汉字(中文)方法

方法一：根据ASCII码转换，GB2312库对多音字也无能为力。

GB2312标准共收录6763个汉字，不在范围内的汉字是无法转换，如：中国前总理朱镕基的“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区为特殊符号。
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：没有使用大文字库，文件相对较小，没有使用正则表达式，性能相对较高。支持首字母转换。
缺点：没有在GB2312中收录的汉字无法转换，多音字无法识别。
（如果对拼音转换要求不高的朋友，建议使用这个。）

方法二：根据拼音组合数组检索
