PHP处理中文二三例

首页 > PHP >

在网上看到一个贴子,是说利用16进制输出所有中文,例子如下:

PHP代码
  1. <?php  
  2. $begin = hexdec ( " 4e00 " ); // 16进制转化为10进制  
  3. $end = hexdec ( " 9fa5 " );  
  4. $a = '["' ;  
  5. for ( $i = $begin ; $i <= $end ; $i ++ ) {  
  6.     $a .= ' \u ' . dechex ( $i );  
  7.     if ( $i % 10 == 0 ) {  
  8.         $a .= " <br> " ; 
  9.     } 
  10. } 
  11. $a .= ' "] ' ;  
  12. print_r (json_decode( $a ));  
  13. ?>  

看到这个例子,相信也能看得出了,那两个数字是不是与网上那种正则判断中文的很象啊。

由于json_encode转换中文时会把中文全部转换成16进制,这样在输出的时候就不会因为浏览器的字符集不支持而出现问题。所以同样的,利用decode也就相当于把这些16进制转换成中文了。其实并不需要这么复杂,只要在前面加上&#后面加上;就可以输出中文了。

看到这样的代码后想起昨天一个根据.net程序改的读取中文字的拼音的程序。

这是根据网上的例子改写而来,其实BUG不少,作业的作,是认不出的。还有GBK的字符也是认不出拼音的(好象GBK里的一些特殊字符的拼音规则和上面的数组并不一致)

不过,这些都算是我的备份吧。呵呵,同样,如果对拼音要求不高的朋友也可以拿来用用。
