看个简单的实例

<?php教程
$dbname = 'mysql_dbname';

if (!mysql_connect('mysql_host', 'mysql_user', 'mysql_password')) {
    echo 'Could not connect to mysql';
    exit;
}

$sql = "SHOW TABLES FROM $dbname";
$result = mysql_query($sql);

if (!$result) {
    echo "DB Error, could not list tablesn";
    echo 'MySQL Error: ' . mysql_error();
    exit;
}

while ($row = mysql_fetch_row($result)) {
    echo "Table: {$row[0]}n";
}

mysql_free_result($result);
?>

只是一个简单的说明：

mysql的名单桌改变你的主动数据库教程中。

例如：

<?php
//set databse context to db1
mysql_select_db("db1");

//list database tables from db2
mysql-list-tables("db2");
?>

<?
 
  mysql_connect("localhost", "login", "passwd") or
         die("Cannot connect: " . mysql_error());
   
    mysql_select_db("db_name");
 
  $res = mysql_query("SHOW TABLE STATUS LIKE 'table_name' ") or die(mysql_error());
 
  $row_res = mysql_fetch_array($res);
  echo $row_res[Auto_increment];
 ?>
