调查:

mysql_query('DESCRIBE '.$table);

你可能还想检查mysql_fetch_array()，如下所示:

$rs = mysql_query($sql);
while ($row = mysql_fetch_array($rs)) {
//$row[0] = 'First Field';
//$row['first_field'] = 'First Field';
}

调查:

mysql_query('DESCRIBE '.$table);

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
)

Mysqli fetch_field()为我工作:

if ($result = $mysqli -> query($sql)) {
  // Get field information for all fields
  while ($fieldinfo = $result -> fetch_field()) {
    printf("Name: %s\n", $fieldinfo -> name);
    printf("Table: %s\n", $fieldinfo -> table);
    printf("Max. Len: %d\n", $fieldinfo -> max_length);
  }
  $result -> free_result();
}

MySQL函数 描述表 应该把你带到你想去的地方(把你的表名输入“table”)。您必须对输出进行一些解析，但这非常简单。我记得，如果执行该查询，PHP查询结果访问函数将以列名作为键，该函数通常会提供一个键-值对。但我已经有一段时间没有使用PHP了，所以不要强迫我这么做。：）
