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';
}

您可以使用以下简单的命令获取整个表结构。

DESC TableName

或者您可以使用以下查询。

SHOW COLUMNS FROM TableName

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';
}

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!

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']
