mysql_list_fields函数可能会引起您的兴趣;但是，正如手册所述:

该函数不建议使用。它是 最好使用mysql_query()来 而不是使用SQL SHOW COLUMNS FROM table [LIKE 'name']语句。

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();
}

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
)

我写了一个简单的php脚本，通过php获取表列: Show_table_columns.php

<?php
$db = 'Database'; //Database name
$host = 'Database_host'; //Hostname or Server ip
$user = 'USER'; //Database user
$pass = 'Password'; //Database user password
$con = mysql_connect($host, $user, $pass);
if ($con) {
    $link = mysql_select_db($db) or die("no database") . mysql_error();
    $count = 0;
    if ($link) {
        $sql = "
            SELECT column_name
            FROM   information_schema.columns
            WHERE  table_schema = '$db'
                   AND table_name = 'table_name'"; // Change the table_name your own table name
        $result = mysql_query($sql, $con);
        if (mysql_query($sql, $con)) {
            echo $sql . "<br> <br>";
            while ($row = mysql_fetch_row($result)) {
                echo "COLUMN " . ++$count . ": {$row[0]}<br>";
                $table_name = $row[0];
            }
            echo "<br>Total No. of COLUMNS: " . $count;
        } else {
            echo "Error in query.";
        }
    } else {
        echo "Database not found.";
    }
} else {
    echo "Connection Failed.";
}
?>

享受吧!
