mysql_query函数到底怎么用

本帖最后由 php_cdsn2 于 2014-11-14 20:49:52 编辑 这个函数一般的解释是查询数据库的连接,可是有人也用它设置数据库编码,但是查了一下w3C官网中对mysql_query的解释http://www.w3school.com.cn/php/func_mysql_query.asp,没有说明关于设置数据库编码的用法。
难道说w3c也在胡弄?
mysql_query('set names  utf8',$conn);
------解决思路----------------------
mysqli->query($sql);
他表示的意思就是执行一条SQL语句,楼主打的MYSQl_query($sql);也一样
$sql你可以自己传语句,mysql_query("set names gbk");只不过就是执行了这条语句,这条语句的作用就是把数据库编码变为GBK;
------解决思路----------------------
对于其它类型的 SQL 语句,mysql_query() 在执行成功时返回 TRUE
这句话不应该有什么理解上的问题吧?

只是对 query 参数的说明中:规定要发送的 SQL 查询
有些欠妥,改为 指令 更为好些

php 有自己的用户手册,建议你下载一份放在手边 http://bbs.csdn.net/topics/390512178
------解决思路----------------------
w3c有的文档,说的还是不够详细的,毕竟只是一个网站,针对基础者学习用的,建议看看专业书籍。
