PHP 計算中文字的筆劃

綜合了 Ning 大大 http://yesning.com 和水電工大大 http://artvine.org/forum/index.php?topic=129.0 的PHP程式樣本後，終於可以寫出個PHP小程式算出中文筆劃數了。 水電工大大的筆劃內碼表是倚天提供的，內容可以在i18n上找的到http://bbs.ecstart.com/thread-15553-1-1.html. 但是現在一般的作業系統都是用 UTF-8作編表，所以單用水電工大大的程式是不行把筆劃算出來的。要採用 Ning大大的iconv()才行。 iconv() 可以把字串string的編碼轉變成另一個格式，我們的情形就是把UTF8轉成Big5. 使用法如下：

完整程式碼如下：

function get_chnnum($word) {
//UTF-8的話先轉成BIG5
$word = iconv(‘utf-8′,’big5//IGNORE’,$word);
if(strlen($word) != 2)
return false;
if(ord($word[0]) < 0xA1)
return false;
$code = hexdec(bin2hex($word));
echo("$coden");
