调查:

mysql_query('DESCRIBE '.$table);

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';

调查:

mysql_query('DESCRIBE '.$table);

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。

如果你喜欢的话，还有这个:

mysql_query('SHOW COLUMNS FROM tableName'); 

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!
