我覺得這個劇本將有助於您在百忙dabase備份
<?php
backup_tables(‘hostaddress’,'dbusername’,'dbpassword’,'dbname’);
/* backup the db OR just a table */
function backup_tables($host,$user,$pass,$name,$tables = ‘*’)
{
$link = mysql_connect($host,$user,$pass);
mysql_select_db($name,$link);
//get all of the tables
if($tables == ‘*’)
{
$tables = array();
$result = mysql_query(‘SHOW TABLES’);
while($row = mysql_fetch_row($result))
{
$tables[] = $row[0];
}
}
else
{
$tables = is_array($tables) ? $tables : explode(‘,’,$tables);
}
//cycle through
foreach($tables as $table)

下面的文章將有助於備份mysql數據庫的SQL文件或GZ format.Also可以備份整個數據庫或特定tables.You必須給主機,數據庫名稱,用戶名和密碼。 [http://faq.pctrickers.com/creating-mysql-database-backup-using-php/](http.pqtrickers.com/creating-mysql-database-backup-using-php/) –
