unfortunately i lost my database a few days ago but luckily i had daily back up.
unfortunately i lost my database(some of my data not whole db) a few days ago but luckily i have daily backup.Today i find out that i have to restore 180 huge database. I need to compare every 180 databases(backups) with the current db(my db) and insert the data that is not any more in my db. AT the beginning i want to use some application like(NAVICAT or db forge studio) but it's not possible that take a lot of time. and also i wanted to compare the SQL test with each other and it's not possible too.
now i have to build a web application(PHP) to restore the databases but i don't know how
i'll be appreciate if anyone help me.
thank you.
If it is a large file, do not open it. Stream it.
$backup = fopen("yourBackUp.sql", "r");
// ...
fclose($backup);
If you have many files, use GLOB
.
foreach(glob(dirname(__FILE__) . '/*.sql', GLOB_BRACE) as $sql) {
$backup = fopen($sql, "r");
// ...
}
If your DB is set-up correctly, you should not be able to insert duplicate rows.
while (($line = fgets($backup)) !== false)
try {
Illuminate\Support\Facades\DB::raw($line);
} catch ( Exception $e ) {
// duplicate row
}
}
Without seeing what you have done and your programmatic issue, we cannot help.
