本文为大家讲解了PHP如何获取mysql数据表的字段名称和详细信息的方法,本文同时还给出了获取数据表结构、列出数据库数据表等方法,感兴趣的朋友可以参考下首先我们需要了解下查询MySQL数据库/表相关信息的SQL语句： SHOW DATABASES //列出 MySQL Server 数据库。 SHOW TABLES [FROM db_name] //列出数据

本文为大家讲解了PHP如何获取 mysql 数据表的字段名称和详细信息的方法,本文同时还给出了获取数据表结构、列出数据库数据表等方法,感兴趣的朋友可以参考下

首先我们需要了解下查询MySQL数据库/表相关信息的SQL语句：

SHOW DATABASES                                //列出 MySQL Server 数据库。

SHOW TABLES [FROM db_name]                    //列出数据库数据表。

SHOW CREATE TABLES tbl_name                    //导出数据表结构。

SHOW TABLE STATUS [FROM db_name]              //列出数据表及表状态信息。

SHOW COLUMNS FROM tbl_name [FROM db_name]     //列出资料表字段

SHOW FIELDS FROM tbl_name [FROM db_name]，DESCRIBE tbl_name [col_name]。

SHOW FULL COLUMNS FROM tbl_name [FROM db_name]//列出字段及详情

SHOW FULL FIELDS FROM tbl_name [FROM db_name] //列出字段完整属性

SHOW INDEX FROM tbl_name [FROM db_name]       //列出表索引。

SHOW STATUS                                  //列出 DB Server 状态。

SHOW VARIABLES                               //列出 MySQL 系统环境变量。

SHOW PROCESSLIST                             //列出执行命令。

SHOW GRANTS FOR user                         //列出某用户权限

由上述SQL语句可以看到，我们可以使用SHOW FULL COLUMNS来列出字段及详情信息，示例代码：

$rescolumns = mysql_query("SHOW FULL COLUMNS FROM ".TB_NAME."") ;

while($row = mysql_fetch_array($rescolumns)){

//  echo '字段名称：'.$row['Field'].'-数据类型：'.$row['Type'].'-注释：'.$row['Comment'];

//  echo '<br/><br/>';

  print_r($row);

}

打印结果：

Array ( [0] => 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,insert,update,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,insert,update,references [Privileges] => select,insert,update,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,insert,update,references [Privileges] => select,insert,update,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
