How to convert kanji to strings in iso 8859 1 PHP Advanced Discussion

The reason is because of your string s="Lin Wei";The string encoding is not GBK, you can change GBK to UTF-8.

string is=new string("utf-8"),"iso-8859-1");

If you convert a GBK string to an ISO-8859-1 string, and then decode it in GBK format, of course, it's a question mark.

ISO-8859-1 is an English encoding and does not support Chinese encoding.

string s="Lin Wei";

string is=new string("gbk"),"iso-8859-1");

string tempstr = new string("iso-8859-1"), "gbk");

That's it.

To convert a GB2312 format string to ISO-8859-1, you need to use the intermediate auxiliary class byte, the principle is to convert a string into a byte, and then convert the byte into a string and transcode at the same time, of course, pay attention to the capture of exceptions.

This process is broadly divided into 2 steps:

Convert strings to bytes.

Convert byte to a string and set the encoding format to ISO-8859-1.

The operation process is shown in the following figure.

There are many ways to solve this problem, first of all, you can change the encoding of the web page, the transmission encoding and so on to UTF-8, which is the simplest way.

8859-1 is a single-byte encoding, while Chinese is a two-byte encoding, so there will be problems with encoding and can also be encoded by conversion.

Let the resulting string be s1

The converted string is string s2 = new string("iso-8859-1"),"utf-8");

After 2 hours, the problem was finally solved: 1, don't use file get contents(), use this function to get content: function curl($url).

2. Detect that "ISO-8859-1" is not necessarily this code, you need to see what code is marked by people on the web page, for example"gb2312", and then use this function: $data=mb convert encoding($data,"utf-8","gb2312");

Please use the function iconv, or mb convert encoding for specific usage see the manual, if these 2 do not work, please use the following function: function conv utf8 iso8859 7($s) else ; // n-byte character, n>2, discard character

curr_char = "";

else if (ord($s[$i]) 128)}return $out;

Call: echo conv utf8 iso8859 7 ('tenx')
