Example of the php Chinese character conversion function to implement encoding conversion:
- // GBK string test
- $ Str ='Haha';
- Echo $ str .'
';
-
- $ Unistr = unicode_encode ($ str );
- Echo $ unistr .'
'; // <B> Haha </B>
-
- $ Str2 = unicode_decode ($ unistr );
- Echo $ str2 .'
';//Haha
-
- // UTF-8 string test
- $ Utf8_str = iconv ('gbk', 'utf-8', $ str );
- Echo $ utf8_str .'
';//Note: garbled characters of UTF in GBK are displayed! You can switch the encoding test of the browser.
-
- $ Utf8_unistr = unicode_encode ($ utf8_str, 'utf-8 ');
- Echo $ utf8_unistr .'
'; // <B> Haha </B>
-
- $ Utf8_str2 = unicode_decode ($ utf8_unistr, 'utf-8 ');
- Echo $ utf8_str2 .'
';//
-
- // Test other suffixes and prefixes
- $ Prefix_unistr = unicode_encode ($ str, 'gbk', "\ u ",'');
- Echo $ prefix_unistr .'
'; // \ U60 \ u98 \ u62 \ u21704 \ u21704 \ u60 \ u47 \ u98 \ u62
-
- $ Profix_unistr2 = unicode_decode ($ prefix_unistr, 'gbk', "\ u ",'');
- Echo $ profix_unistr2 .'
';//Haha
