Dump the contents of a database

This repo contains an easy to use class to dump a database using PHP. Currently MySQL, PostgreSQL, SQLite and MongoDB are supported. Behind the scenes mysqldump, pg_dump, sqlite3 and mongodump are used.

Here's are simple examples of how to create a database dump with different drivers:

MySQL

Spatie\DbDumper\Databases\MySql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->dumpToFile('dump.sql');

PostgreSQL

Spatie\DbDumper\Databases\PostgreSql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->dumpToFile('dump.sql');

SQLite

Spatie\DbDumper\Databases\Sqlite::create()
    ->setDbName($pathToDatabaseFile)
    ->dumpToFile('dump.sql');

MongoDB

Spatie\DbDumper\Databases\MongoDb::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->dumpToFile('dump.gz');

Requirements

For dumping MySQL-db's mysqldump should be installed.

For dumping PostgreSQL-db's pg_dump should be installed.

For dumping SQLite-db's sqlite3 should be installed.

For dumping MongoDB-db's mongodump should be installed.

Installation

You can install the package via composer:

composer require spatie/db-dumper

Usage

This is the simplest way to create a dump of a MySql db:

Spatie\DbDumper\Databases\MySql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->dumpToFile('dump.sql');

If you're working with PostgreSQL just use that dumper, most methods are available on both the MySql. and PostgreSql-dumper.

Spatie\DbDumper\Databases\PostgreSql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->dumpToFile('dump.sql');

If the mysqldump (or pg_dump) binary is installed in a non default location you can let the package know by using thesetDumpBinaryPath()-function:

Spatie\DbDumper\Databases\MySql::create()
    ->setDumpBinaryPath('/custom/location')
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->dumpToFile('dump.sql');

If your application is deployed and you need to change the host (default is 127.0.0.1), you can add the setHost()-function:

Spatie\DbDumper\Databases\MySql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->setHost($host)
    ->dumpToFile('dump.sql');

Dump specific tables

Using an array:

Spatie\DbDumper\Databases\MySql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->includeTables(['table1', 'table2', 'table3'])
    ->dumpToFile('dump.sql');

Using a string:

Spatie\DbDumper\Databases\MySql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->includeTables('table1, table2, table3')
    ->dumpToFile('dump.sql');

Don't use column_statics table with some old version of MySql service.

In order to use "--column-statistics=0" as option in mysqldump command you can use doNotUseColumnStatistics() method.

If you have installed mysqldump 8, it queries by default column_statics table in information_schema database. In some old version of MySql (service) like 5.7, this table it not exists. So you could have an exception during the execution of mysqldump. To avoid this, you could use doNotUseColumnStatistics() method.

Spatie\DbDumper\Databases\MySql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->doNotUseColumnStatistics()
    ->dumpToFile('dump.sql');

Excluding tables from the dump

Using an array:

Spatie\DbDumper\Databases\MySql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->excludeTables(['table1', 'table2', 'table3'])
    ->dumpToFile('dump.sql');

Using a string:

Spatie\DbDumper\Databases\MySql::create()
    ->setDbName($databaseName)
    ->setUserName($userName)
    ->setPassword($password)
    ->excludeTables('table1, table2, table3')
    ->dumpToFile('dump.sql');

Do not write CREATE TABLE statements that create each dumped table.

$dumpCommand = MySql::create()
    ->setDbName('dbname')
    ->setUserName('username')
    ->setPassword('password')
    ->doNotCreateTables()
    ->getDumpCommand('dump.sql', 'credentials.txt');

Adding extra options

If you want to add an arbitrary option to the dump command you can use addExtraOption

$dumpCommand = MySql::create()
    ->setDbName('dbname')
    ->setUserName('username')
    ->setPassword('password')
    ->addExtraOption('--xml')
    ->getDumpCommand('dump.sql', 'credentials.txt');

If you're working with MySql you can set the database name using --databases as an extra option. This is particularly useful when used in conjunction with the --add-drop-database mysqldump option (see the mysqldump docs).

$dumpCommand = MySql::create()
    ->setUserName('username')
    ->setPassword('password')
    ->addExtraOption('--databases dbname')
    ->addExtraOption('--add-drop-database')
    ->getDumpCommand('dump.sql', 'credentials.txt');

With MySql, you also have the option to use the --all-databases extra option. This is useful when you want to run a full backup of all the databases in the specified MySQL connection.

$dumpCommand = MySql::create()
    ->setUserName('username')
    ->setPassword('password')
    ->addExtraOption('--all-databases')
    ->getDumpCommand('dump.sql', 'credentials.txt');

Please note that using the ->addExtraOption('--databases dbname') or ->addExtraOption('--all-databases') will override the database name set on a previous ->setDbName() call.

Using compression

If you want to compress the outputted file, you can use one of the compressors and the resulted dump file will be compressed.

There is one compressor that comes out of the box: GzipCompressor. It will compress your db dump with gzip. Make sure gzip is installed on your system before using this.

$dumpCommand = MySql::create()
    ->setDbName('dbname')
    ->setUserName('username')
    ->setPassword('password')
    ->useCompressor(new GzipCompressor())
    ->dumpToFile('dump.sql.gz');

Creating your own compressor

You can create you own compressor implementing the Compressor interface. Here's how that interface looks like:

namespace Spatie\DbDumper\Compressors;

interface Compressor
{
    public function useCommand(): string;

    public function useExtension(): string;
}

The useCommand should simply return the compression command the db dump will get pumped to. Here's the implementation of GzipCompression.

namespace Spatie\DbDumper\Compressors;

class GzipCompressor implements Compressor
{
    public function useCommand(): string
    {
        return 'gzip';
    }

    public function useExtension(): string
    {
        return 'gz';
    }
}
