这对我很有效。

$sql = "desc MyTableName";
$result = @mysql_query($sql);
while($row = @mysql_fetch_array($result)){
    echo $row[0]."<br>";
}

你可以使用DESCRIBE:

DESCRIBE my_table;

或者在更新的版本中，你可以使用INFORMATION_SCHEMA:

SELECT COLUMN_NAME
  FROM INFORMATION_SCHEMA.COLUMNS
  WHERE TABLE_SCHEMA = 'my_database' AND TABLE_NAME = 'my_table';

或者你可以使用SHOW COLUMNS:

SHOW COLUMNS FROM my_table;

或者在一行中获取带逗号的列名:

SELECT group_concat(COLUMN_NAME)
  FROM INFORMATION_SCHEMA.COLUMNS
  WHERE TABLE_SCHEMA = 'my_database' AND TABLE_NAME = 'my_table';

这对我很有效。

$sql = "desc MyTableName";
$result = @mysql_query($sql);
while($row = @mysql_fetch_array($result)){
    echo $row[0]."<br>";
}

下面的SQL语句几乎是等价的:

SELECT COLUMN_NAME
  FROM INFORMATION_SCHEMA.COLUMNS
 WHERE table_name = 'tbl_name'
  [AND table_schema = 'db_name']
  [AND column_name LIKE 'wild']

SHOW COLUMNS
FROM tbl_name
[FROM db_name]
[LIKE 'wild']

参考:INFORMATION_SCHEMA列

我需要列名作为平面数组，而其他答案返回关联数组，所以我使用:

$con = mysqli_connect('localhost',$db_user,$db_pw,$db_name);
$table = 'people';

/**
* Get the column names for a mysql table
**/

function get_column_names($con, $table) {
  $sql = 'DESCRIBE '.$table;
  $result = mysqli_query($con, $sql);

  $rows = array();
  while($row = mysqli_fetch_assoc($result)) {
    $rows[] = $row['Field'];
  }

  return $rows;
}

$col_names = function get_column_names($con, $table);

$col_names现在等于:

(
    [0] => name
    [1] => parent
    [2] => number
    [3] => chart_id
    [4] => type
    [5] => id
)

在mysql中，通过关键字或查询来获取列的详细信息和表的结构

1.DESC table_name

2.描述table_name

3.显示table_name中的列

4.创建表table_name

5.解释table_name
