我正在尝试在数据库中存储“£”。我还在集合中将该字段标记为utf8_general_ci，但另存为�。我还在元标记HTML文件中设置了UTF-8。这里缺少什么
- - - - - - - - -编辑 - - - - - -
我检查了一下，该页面上有一个编辑器（Rich Text）。如果我使用此编辑器保存数据，则它将生成-但如果使用文本框，则可以正常工作。我不知道这有什么问题以及如何调试此问题
$query = "insert into field_master set fk_t_id = '".$_POST['t_id']."', fk_g_id = '".$_POST['g_id']."', fk_f_id = '".$_POST['f_id_'.$inc_i.'_'.$inc_j]."'".$str.", field_value = '".$field_value."', field_required = '".$required."', fk_section_id = '".$_POST['section_id_'.$inc_i]."', section_order = '".$_POST['section_order_'.$inc_i]."', field_order = '".$_POST['temp_order_'.$inc_i.'_'.$inc_j]."'";
$smt = $class->dbh->prepare($query);
$smt->execute();
最佳答案
The examples shown here assume use of the utf8 character set and utf8_general_ci collation.
Specify character settings per database. To create a database such that its tables will use a given default character set and collation for data storage, use a CREATE DATABASE statement like this:
CREATE DATABASE mydb
DEFAULT CHARACTER SET utf8
DEFAULT COLLATE utf8_general_ci;
Tables created in the database will use utf8 and utf8_general_ci by default for any character columns.
Applications that use the database should also configure their connection to the server each time they connect. This can be done by executing a SET NAMES 'utf8' statement after connecting. The statement can be used regardless of connection method: The mysql client, PHP scripts, and so forth.
In some cases, it may be possible to configure the connection to use the desired character set some other way. For example, for connections made using mysql, you can specify the --default-character-set=utf8 command-line option to achieve the same effect as SET NAMES 'utf8'.
If you change the default character set or collation for a database, stored routines that use the database defaults must be dropped and recreated so that they use the new defaults. (In a stored routine, variables with character data types use the database defaults if the character set or collation are not specified explicitly.
Specify character settings at server startup. To select a character set and collation at server startup, use the --character-set-server and --collation-server options. For example, to specify the options in an option file, include these lines:
[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci
These settings apply server-wide and apply as the defaults for databases created by any application, and for tables created in those databases.
I hope these information would be useful to you.
