Two PHP database backup program codes_PHP tutorial

Xiaosheng collected two PHP database backup programs today. The functions that can be completed here are: 1. Back up the specified data table, 2. Package into a zip file, 3. Send to the specified email address, that’s all the basic functions

See how to use it below:

The code is as follows

Copy code

代码如下	复制代码
error_reporting(0);//消灭万恶的php报警提示 //设定邮箱 $options = array('email' => array('email1', 'email2'), 'folder' => './backup/', 'mysql' => array('localhost', 'user', 'password', 'db'));   $b = new Backup($options);     // 提交备份命令   if(isset($_POST['backup']))   {    // 开始备份    $b->backupDB();   }   // 显示备份表   $b->outputForm(); ?>

error_reporting(0);//Eliminate all evil php alarm prompts
//Set email
$options = array('email' => array('email1', 'email2'),
'folder' => './backup/',
'mysql' => array('localhost', 'user', 'password', 'db'));

$b = new Backup($options);

// Submit backup command
if(isset($_POST['backup']))
{
// Start backup
$b->backupDB();
}
// Display backup table
$b->outputForm();
?>

Concrete class implementation:

The code is as follows

Copy code
