关于PHP操作MYSQL数据库,乱码的问题,高手达人们,看看帮忙解决一下
我的情况如下:
我的网页是GB2312编码的,我的数据库的编码是UTF8的,如果我想让数据库里的内容读到网页上,要加上mysql_query("set names gb2312") 这句话,可以解决乱码的问题,这样显示在网页上的就不是乱码了.
但是当我在网页中加入一条插入数据库内容的语句,如果我不加mysql_query("set names gb2312")这句话,他插入数据库的内容是乱码,因为数据库的编码是UTF8,网页中的内容是GB2312编码,所以他显示乱码
但是我加上mysql_query("set names gb2312")这句话后,加入数据库的内容就不会显示乱码
我不明白的是mysql_query("set names gb2312")这句话,可以解决插入到UTF8数据库解决汉字乱码的问题?
mysql_query("set names gb2312")这句话不是设置字符集为GB2312吗?为什么插入UTF8数据库里不会乱码?相反我不加这句话就会显示乱码呢?
高手们帮帮小弟吧
------解决方案--------------------
set names 是用来设置客户端的字符集，与服务端没关系，
set names gb2312 等于是插入之前告诉数据库我是以gb2312的编码进来的，数据库根据进来时的编码来处理它，如果不加这句，数据库就不知道它是以什么编码进来的，这样就出现乱码了
同样道理 查询的时候，用set names gb2312 告诉数据库，我想得到gb2312编码的数据，你给我返回gb2312编码数据吧，数据库就给出gb2312的数据了，如果不加，给出的就是utf-8，显示到网页上就成乱码了

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AMPHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AMIn PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
