How does dedecms perform encoding conversion?

dedecms method for encoding conversion: 1. Create a sample file; 2. Define a variable "$utf8_str" with a value of "UTF-8 encoded string"; 3. Use "iconv("UTF- 8", "GBK//IGNORE", $utf8_str)" syntax for encoding conversion; 4. Use "mb_convert_encoding($utf8_str, "GBK", "UTF-8")" syntax for encoding conversion, and echo outputs the result.

The operating system of this tutorial: Windows 10 system, DedeCMS version 5.7.109, Dell G3 computer.

dedecms encoding conversion method can be achieved through PHP's built-in function `iconv()` or `mb_convert_encoding()`.

The usage of these two functions is as follows:

// 使用iconv()函数进行编码转换 $utf8_str = "UTF-8编码字符串"; $gbk_str = iconv("UTF-8", "GBK//IGNORE", $utf8_str); echo $gbk_str; // 使用mb_convert_encoding()函数进行编码转换 $utf8_str = "UTF-8编码字符串"; $gbk_str = mb_convert_encoding($utf8_str, "GBK", "UTF-8"); echo $gbk_str;

In the above code example, UTF-8 encoded string is converted into GBK encoded string, where `//IGNORE` The parameter indicates that illegal characters are ignored.

If you want to perform full-site encoding conversion in dedecms, it is recommended to add the following code to the global template file:

// 开启输出缓存 ob_start(); // 转换输出内容的编码 header("Content-type: text/html; charset=GBK"); $content = ob_get_contents(); ob_clean(); echo iconv("UTF-8", "GBK//IGNORE", $content);

In this way, all page output of the website can be converted to GBK encoding. Note that this code should be added in global template files such as `header.php`.
