复制代码例子,php汉字转换函数的范例,实现编码转换:
- //GBK字符串测试
- $str = '哈哈';
- echo $str.'
'; -
- $unistr = unicode_encode($str);
- echo $unistr.'
'; // <b>哈哈</b> -
- $str2 = unicode_decode($unistr);
- echo $str2.'
'; //哈哈 -
- //UTF-8字符串测试
- $utf8_str = iconv('GBK', 'UTF-8', $str);
- echo $utf8_str.'
'; // 鍝堝搱 注:UTF在GBK下显示的乱码!可切换浏览器的编码测试 -
- $utf8_unistr = unicode_encode($utf8_str, 'UTF-8');
- echo $utf8_unistr.'
'; // <b>哈哈</b> -
- $utf8_str2 = unicode_decode($utf8_unistr, 'UTF-8');
- echo $utf8_str2.'
'; // 鍝堝搱 -
- //其它后缀、前缀测试
- $prefix_unistr = unicode_encode($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.'
'; //哈哈
