Php Chinese character conversion GBK-Big5. The conversion of Chinese characters in php has always been quite troublesome. First, we should say two points: 1. the traditional Chinese version of GBK is not Big5, but generally the traditional Chinese version has a corresponding Big Code 2. a gbk code does not necessarily have a corresponding Big5 code. it is always troublesome to convert Chinese characters in php.
There are two points:
1. GBK traditional Chinese characters are not Big5, but generally traditional Chinese characters have Big codes.
2. a GBK code does not necessarily have a corresponding Big5 code, so it is generally irreversible conversion.
This class has three built-in functions.
QswhStr format string
QswhFile format a file
QswhDir format all files in the Directory (except for. qswh, which is the backup of the original document)

Function qswhFile ($ filename, $ fail = "?? "){
/***** (Qiushuiwuhen 2002-9-6 )******/
If (! File_exists ($ filename. ". qswh") copy ($ filename, $ filename. ". qswh ");
$ Fp = fopen ($ filename, "r + ");
$ Tmp = fread ($ fp, filesize ($ filename ));
Rewind ($ fp );
Fwrite ($ fp, $ this-> qswhStr ($ tmp, $ fail ));
Fclose ($ fp );
}
Function qswhDir ($ dirname, $ fail = "?? "){
/***** (Qiushuiwuhen 2002-9-6 )******/
$ D = dir ($ dirname );
While ($ entry = $ d-> read ()){
If ($ entry = "." | $ entry = "...") continue;
$ Entry = $ dirname. "/". $ entry;
If (is_dir ($ entry ))
$ This-> qswhDir ($ entry, $ fail );
Else {
If (substr ($ entry,-5 )! = ". Qswh") $ this-> qswhFile ($ entry, $ fail );
}
}
$ D-> close ();
Return $ c;
}
}
Example:
$ Words = "no hate in autumn ";
$ Qswh = new qswhBig5 ("qswhBig5.php"); // qswhBig5.php, which saves parameters
Echo (" Please select the encoding Big5 to view :". $ qswh-> qswhStr ($ words); <br> echo ("encoding 1 Directory :". $ qswh-> qswhDir ("test"); <br> echo ("encode a File :". $ qswh-> qswhFile ("index.htm"); <br> Usage: <br> The second parameter in qswhStr indicates the word that will be replaced if no corresponding Big5 is found, if it is empty, retain the word <br>. after formatting the file, remember to modify the content-type in <meta to Big.
