PHP获取mysql数据表的字段名称和详细信息的方法

打印结果： 代码如下: id [Field] => id [1] => char(2) [Type] => char(2) [2] => utf8_general_ci [Collation] => utf8_general_ci [3] => NO [Null] => NO [4] => PRI [Key] => PRI [5] => [Default] => [6] => [Extra] => [7] => select,insert,update,references [Privileges] => select,references [8] => [Comment] => )

Array ( [0] => title [Field] => title [1] => char(50) [Type] => char(50) [2] => utf8_general_ci [Collation] => utf8_general_ci [3] => YES [Null] => YES [4] => [Key] => [5] => [Default] => [6] => [Extra] => [7] => select,references [8] => 建议存储：标题、姓名等信息 [Comment] => 建议存储：标题、姓名等信息 )

Array ( [0] => des [Field] => des [1] => varchar(255) [Type] => varchar(255) [2] => utf8_general_ci [Collation] => utf8_general_ci [3] => YES [Null] => YES [4] => [Key] => [5] => [Default] => [6] => [Extra] => [7] => select,references [8] => [Comment] => )

补充说明信息：

当然你也可以通过mysql_list_fields — 列出 MySQL 结果中的字段。mysql_list_fields() 取得给定表名的信息，参数是数据库名和表名，返回一个结果指针。

但是，mysql_list_fields() 函数已过时。最好用 mysql_query() 来发出一条 SHOW COLUMNS FROM table [LIKE 'name'] 的 SQL 语句来代替。详细可参考PHP帮助文档：PHP: mysql_list_fields - Manua
