Php MySQL编码解析错误
我试图用这个命令添加一些文本,包含在我的php文件中:Php MySQL编码解析错误,php,mysql,utf-8,Php,Mysql,Utf 8,我试图用这个命令添加一些文本,包含在我的php文件中: $sql = "INSERT INTO $this->table_name_category (name, marker_icon) VALUES ('".$name."', '".$marker_icon."')"; 用英文字符看起来一切都很好,但用希腊文字符,解析后的文本被转换成问号“??” 还有什么我必须处理的吗?有没有办法告诉INSERT命令使用UTF8来支持希腊字符 提前谢谢 我的数据库设置为utf8\U unicode\
$sql = "INSERT INTO $this->table_name_category (name, marker_icon) VALUES ('".$name."', '".$marker_icon."')";
用英文字符看起来一切都很好,但用希腊文字符,解析后的文本被转换成问号“??”
还有什么我必须处理的吗?有没有办法告诉INSERT命令使用UTF8来支持希腊字符
提前谢谢
我的数据库设置为utf8\U unicode\U ci(表也是)

需要检查的两件事是连接和列。列可以有自己的字符集
在mysql中执行任何查询或CRUD之前,请发出以下命令
"SET NAMES utf8"
"SET CHARACTER SET utf8"
在PHP中
mysql_query("SET NAMES utf8");
要确保所有内容都在UTF-8中,并且您使用PDO。。。将您的PDO连接修改为此
取决于您使用的API
$pdo = new PDO(
'mysql:host=hostname;dbname=defaultDbName',
'username',
'password',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "utf8")
);
参考:
1.使用show create table X查看表的编码
比如:
mysql> show create table user;
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| user | CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL,
`password` varchar(64) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8 |
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
2.如果字符集不是utf8,则将其更改为utf8
mysql> alter table y character set 'utf8';
不管怎样,你能告诉我们你是否正在使用PDO吗?不,我没有。我使用的命令是这样的:函数add_category($criteria=array()){$name=$criteria['name'];$marker_icon=$criteria['marker_icon'];$sql=“INSERT INTO$this->table_name_category(name,marker_icon)值('.''''.'''.'''.'''.$this->wpdb->query($sql);}),您可以编辑您的/etc/my.cnf
文件,添加init connect='SET NAMES utf8'
,以避免每次从PHP连接到MySQL时都显式设置它。@jackflash非常好的建议。但是我们有一个主机,可以在具有特定编码的数据库上工作,特别是在日本数据库上,这些数据库总是将信息编码到SJIS
谢谢!然而,我试着这样添加它,但它不起作用:函数add_category($criteria=array()){mysql_query(“SET NAMES utf8”);$name=$criteria['name'];$marker_icon=$criteria['marker_icon'];$sql=“INSERT INTO$this->table_name_category(name,marker_icon)值(“““,”)”;$this->wpdb->query($sql)}你能给我们更多的代码吗?并将其更新到您的问题。根据您使用的API,请勿在DSN中使用mysql\u SET\u charset
或charset=utf8
。请参阅已尝试的ALTER TABLE wp_store_wpress_category CHARGE SET utf8,COLLATE utf8_unicode_ci;在没有luckplease的情况下,后期创建表输出。若你们从终端向sql中插入数据,你们能正常读取它吗,还是它仍然是。如果您可以正常看到,那么是web层在某个地方破坏了输入。检查html页面中的内容类型-是否匹配,例如是否为uf8?如果我从phpmyadmin手动编辑该字段,我会收到一条警告:警告:#1366错误的字符串值:“\xCE\xB4\xCF\x83\xCE\xB4…”用于第1行的“name”列-但在我的网站上,其他所有内容都可以使用希腊字符正常工作。
