The principle is very simple, because gb2312/gbk is a Chinese byte, the two bytes have a value range, while the Chinese character in UTF-8 is three bytes, and each byte also has a value range. English, regardless of the encoding, is less than 128, only occupies one byte (excluding the full width) When PHP processes the page, we use iconv or mb_convert functions for character set conversion. However, this is actually a prerequisite. That is, we must know in and out encoding in advance before we c

About the BIG5-HKSCS solution. It is very hard to find that PHP has always supported the problem of HKSCS which has been difficult for a long time. But not the HK-SCS, the BIG5-HKSCS. The following is a solution to the HK increment character set: the HTML dataset was found to be very bitter, and PHP has always supported the problem of HKSCS which has been difficult to understand. But not the HK-SCS, the BIG5-HKSCS. The following is a solution to solve the HK increment character set: The HTML fac

Use php to convert the codes between gb2312 and unicode. The following example shows how to convert gb2312 from unicode to iconv functions after php4.3.1, you only need to write a uft8-to-unicode conversion code between gb2312 and unicode. The following example converts gb2312 to "full ". The iconv function after php4.3.1 is very useful, but you only need to write a conversion function from uft8 to unicode. Check the table (gb2312.txt ). The code is as follows: $ Text = "";Preg_match_all ("
