PHP汉字转拼音的两种方法+PHP提取汉字(中文)方法

2020/7/24 10:59:45 文章标签:

 

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。)

PHP取得汉字(中文):

 

 

function getChinese($str,$charset='utf8'){

	if($charset=='gb2312'){
		if(!preg_match_all("/^[".chr(0xa1)."-".chr(0xff)."]+/",$str,$match)){

	}
	//
	if($charset=='utf8'){
		if(!preg_match_all("/[\x{4e00}-\x{9fa5}]+/u",$str,$match)){
			return false;
		}
		return implode('',$match[0]);
	}
	return false;

}

PHP取得汉字拼音字母数组标点:

 

//取得字符串中汉字字符数字下划线和短连接符、逗号、句号、分号、冒号、书名号、问号等非特殊字符
