Php 导出SQL数据库

在phpMyAdmin中，有一个选项可以将整个表（或数据库）导出到.SQL文件中

我不知道他们是如何做到这一点的，因为我想把它放在CRON的工作中，每天和每周备份数据库。但是似乎没有任何一个命令可以做到这一点，是吗？

是的，mysqldump：

不过，您需要具有服务器访问权限才能使用它。此外，如果您喜欢冒险，并且希望保持一致的备份，请查找主/从设置的信息

您可以创建一个shell脚本，并通过cron作业调用该脚本。

使用mysqldump

  mysqldump -h hostname -u user -pPassword dbname >/path/to/file

如果主机是本地主机，则主机是可选的。根据某些设置，用户和密码也可能是可选的。注意：您可能需要添加日期名称

  mysqldump -h hostname -u root mydb > /path/to/backup/$(date +%a)

您可以使用PHP运行这些命令，将下面的代码复制到一个文件中，并使用cron job执行它

<?php

//DONT EDIT BELOW THIS LINE
//Export the database and output the status to the page
$command='mysql -h' .$mysqlHostName .' -u' .$mysqlUserName .' -p' .$mysqlPassword .' ' .$mysqlDatabaseName .' < ' .$mysqlImportFilename;
exec($command,$output=array(),$worked);
switch($worked){
    case 0:
        echo 'Import file <b>' .$mysqlImportFilename .'</b> successfully imported to database <b>' .$mysqlDatabaseName .'</b>';
        break;
