[英]How to backup/export the connected Database database.sql file in laravel?
I have viewed all the topics available for this question, but not getting any acurate answer... anybody got clear idea to backup the current database in.sql file and download it?我已经查看了这个问题的所有可用主题,但没有得到任何准确的答案......有人清楚地知道备份当前数据库 in.sql 文件并下载它吗?

I've tweaked @Abdelhakim Ezzahouri's code, to use Laravel's existing connection to DB instead of connecting again, entering credentials, and installing PDO, if it's not installed already.我已经调整了@Abdelhakim Ezzahouri 的代码,以使用 Laravel 与 DB 的现有连接,而不是再次连接、输入凭据并安装 PDO(如果尚未安装)。

one of the best solution最好的解决方案之一
fisrt of all install spatie on local serverhttps://spatie.be/docs/laravel-backup/v6/installation-and-setup首先在本地服务器上安装spatiehttps://spatie.be/docs/laravel-backup/v6/installation-and-setup
now check backup working or not php artisan backup:run
现在检查备份工作与否
php artisan backup:run
if backup success then u can also take it on cpanel for this go ro app/Console/Kernal.php and register this command如果备份成功,那么您也可以在 cpanel 上为此 go ro app/Console/Kernal.php 并注册此命令
protected function schedule(Schedule $schedule) { $schedule->command('backup:run')->everyMinute(); }
now open your cpanel and open cron job and there register this command现在打开你的cpanel并打开cron作业并在那里注册这个命令
/usr/local/bin/php /home/replaceyourdirectoryname/public_html/artisan backup:run > /dev/null 2>&1
now you are successful able to take backup on live server现在您可以成功地在实时服务器上进行备份
now for on clcik download现在在 clcik 上下载
<a href="{{ route('download') }}" class="btn btn-sm btn-primary"><i class="fa fa-download"></i>Download Backup</a>
register route Route::get('/download/','DownloadController@download')->name('download');
注册路由
Route::get('/download/','DownloadController@download')->name('download');
and finally controller最后是 controller
<?php namespace App\Http\Controllers; use Illuminate\Support\Facades\Artisan; class DownloadController extends Controller{ public function download(){ Artisan::call('backup:run'); $path = storage_path('app/laravel-backup/*'); $latest_ctime = 0; $latest_filename = ''; $files = glob($path); foreach($files as $file) { if (is_file($file) && filectime($file) > $latest_ctime) { $latest_ctime = filectime($file); $latest_filename = $file; } } return response()->download($latest_filename); }
} }
Thanks for @Abdelhakim Ezzahraoui for your solution.感谢@Abdelhakim Ezzahraoui 的解决方案。 i have just change some code.
我刚刚更改了一些代码。 so here you can backup all table.
所以在这里你可以备份所有表。 but if you want specific then you set that table name.
但是如果你想要具体的,那么你设置那个表名。
function backupDatabase()
{
//ENTER THE RELEVANT INFO BELOW
$mysqlHostName = env('DB_HOST');
$mysqlUserName = env('DB_USERNAME');
$mysqlPassword = env('DB_PASSWORD');
$DbName = env('DB_DATABASE');
$file_name = 'database_backup_on_' . date('y-m-d') . '.sql';
$queryTables = \DB::select(\DB::raw('SHOW TABLES'));
foreach ( $queryTables as $table )
{
foreach ( $table as $tName)
{
$tables[]= $tName ;
}
}
// $tables = array("users","products","categories"); //here your tables...
$connect = new \PDO("mysql:host=$mysqlHostName;dbname=$DbName;charset=utf8", "$mysqlUserName", "$mysqlPassword",array(\PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));
$get_all_table_query = "SHOW TABLES";
$statement = $connect->prepare($get_all_table_query);
$statement->execute();
$result = $statement->fetchAll();
$output = '';
foreach($tables as $table)
{
$show_table_query = "SHOW CREATE TABLE " . $table . "";
$statement = $connect->prepare($show_table_query);
$statement->execute();
$show_table_result = $statement->fetchAll();
foreach($show_table_result as $show_table_row)
{
$output .= "\n\n" . $show_table_row["Create Table"] . ";\n\n";
}
$select_query = "SELECT * FROM " . $table . "";
$statement = $connect->prepare($select_query);
$statement->execute();
$total_row = $statement->rowCount();
for($count=0; $count<$total_row; $count++)
{
$single_result = $statement->fetch(\PDO::FETCH_ASSOC);
$table_column_array = array_keys($single_result);
$table_value_array = array_values($single_result);
$output .= "\nINSERT INTO $table (";
$output .= "" . implode(", ", $table_column_array) . ") VALUES (";
$output .= "'" . implode("','", $table_value_array) . "');\n";
}
}
$file_handle = fopen($file_name, 'w+');
fwrite($file_handle, $output);
fclose($file_handle);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . basename($file_name));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file_name));
ob_clean();
flush();
readfile($file_name);
unlink($file_name);
}
If you wanted to download backup on the fly, use this code after your backup content.如果您想即时下载备份,请在备份内容后使用此代码。
$headers = [
'Content-Disposition' => sprintf('attachment; filename="%s"', 'backup.sql'),
];
return response()->make($output, 200, $headers);
go to your database server and select the database and click on export after export click Go . go 到您的数据库服务器和 select 数据库并单击导出后单击Go 。
your database downloaded in你的数据库下载在
databasename.sql.
数据库名称.sql。
i hope it will be help you.我希望它会帮助你。
