PHP 使用文件方式导入导出整个MYSQL数据库的实现方法

PHP mysql以文件形式导入导出整个数据库，感兴趣的小伙伴，下面一起跟随512笔记的小编罗X来看看吧。
经测试代码如下：

<?php/** * 文件方式导入导出整个MYSQL数据库 * * @param 使用时一定要注意是否是处于导入状态，如果是导入操作，一定要先备份数据库，否则数据会被清空。。 * @author 512笔记 www.512pic.com **//* 导出SELECT * INTO OUTFILE 'c:/name.txt'FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\''LINES TERMINATED BY '\n'FROM zones;导入LOAD DATA INFILE 'c:/name.txt' INTO TABLE zones  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\''LINES TERMINATED BY '\n';*/ set_time_limit(0);define(HOST,'127.0.0.1');define(USER,'root');define(PWD,'');define(DBNAME,'test');define(DIR,'E:/www/mysql_data/');//0为导入 1为导出 2为修复 define(OPERATION,1);mysql_connect(HOST,USER,PWD) ordie("Could not connect: " . mysql_error());mysql_select_db(DBNAME) ordie("Could not select db: " . mysql_error());$result = mysql_query("show tables");if(!is_dir(DIR)){ die('Folder does not exist');}if(OPERATION==0){ //前提：需要先前导入表结构 //导出命令：mysqldump -u root -p -d test>test.sql while ($row = mysql_fetch_array($result, MYSQL_NUM)) {  $fileName=DIR.$row[0].".txt";  if(file_exists($fileName)){   //delete  truncate   $querySql='TRUNCATE TABLE `'.$row[0].'`';   mysql_query($querySql) or   die("Could not truncate table: ". $querySql . mysql_error());      $querySql = "LOAD DATA INFILE '".$fileName."'
