SQL查询的最佳字符集编码是什么？

[英]What is the best charset encoding for sql query?

原文 2015-03-06 13:12:18 8 1 php/ mysql/ utf-8

For example russian characters not reading, accent letters not read. 例如俄语字符不阅读，重音字母不阅读。

I tried with mysqli_set_charset("cp1251") and with utf8 , not working. 我尝试使用mysqli_set_charset("cp1251")和utf8 ，但无法正常工作。

I've tryed to insert string in sql like this htmlentities($str, ENT_QUOTES, "UTF-8"); 我试图像这样的htmlentities($str, ENT_QUOTES, "UTF-8");在sql中插入字符串htmlentities($str, ENT_QUOTES, "UTF-8"); and for accent letters working perfectly but for russian characters the result is like this Øóôóòèíñêèé Ìèõàèë . 对于重音字母来说效果很好，但是对于俄语字符来说，结果就像ØóôóòèíññèèéÌèõàèë 。

Thanks. 谢谢。

It is important to use the same character set in the complete data chain. 在整个数据链中使用相同的字符集非常重要。 Mixed encodings will always cause problems. 混合编码总是会引起问题。

Set the table or column encoding to charset x 将表或列的编码设置为字符集x
Set the database connection encoding to charset x 将数据库连接编码设置为charset x
Set the internal encoding of PHP to charset x or convert the string 将PHP的内部编码设置为charset x或转换字符串
Set the input and output client (mysql console, browser or cli) encoding to charset x 将输入和输出客户端（mysql控制台，浏览器或cli）的编码设置为charset x
When you are using a browser check the encoding which is set in the http header, too. 使用浏览器时，还要检查在HTTP标头中设置的编码。 Depending on the browser this value might overwrite an exisiting meta tag in the html header! 根据浏览器的不同，此值可能会覆盖html标头中的现有meta标签！
