檢測在PHP4

Question

字符串編碼如何檢測字符串編碼，而不在PHP4

Answer 1

MB_ *和iconv功能我不明白，難道你只是使用功能：

/* Detect character encoding with current detect_order */ 
echo mb_detect_encoding($str); 

/* "auto" is expanded to "ASCII,JIS,UTF-8,EUC-JP,SJIS" */ 
echo mb_detect_encoding($str, "auto"); 

/* Specify encoding_list character encoding by comma separated list */ 
echo mb_detect_encoding($str, "JIS, eucjp-win, sjis-win"); 

如上所述在PHP.net manua l？
