My shared web host have some problems with query prepares and I want to enable PDO's emulated prepares, there's no option for this in the config\database.php.
Is there any way I can do that in Laravel?
You can add an "options" array to add options to your Database Connection within config/database.php:
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
// Additional options here
'options' => [PDO::ATTR_EMULATE_PREPARES => true, PDO::MYSQL_ATTR_COMPRESS => true,]
],
You will see I've also switched on MYSQL_ATTR_COMPRESS for my connection.
You can find more information on some of the options they have built in here:

I have use multiple database in my project. But is that possible to use multiple connection in single query in laravel? This is my connection config.
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
'mysql_pdd' => [
'driver' => 'mysql',
'host' => env('DB_PDD_HOST', '127.0.0.1'),
'port' => env('DB_PDD_PORT', '3306'),
'database' => env('DB_PDD_DATABASE', 'forge'),
'username' => env('DB_PDD_USERNAME', 'forge'),
'password' => env('DB_PDD_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
I want to join a tabel in my mysql connection to mysql_pdd table. Is that possible?
Yes, you can but for that you need to put condition, when you want to connect 'mysql' and when 'msql_pdd'.
if (mysql_connection){
$mysql =DB:: reconnect('mysql');
}else if(mysql_pdd_connection){
$mysql_pdd =DB:: reconnect('mysql_pdd');
}
Using $mysql & $mysql_pdd you can perform joins as well by code not by query.
I am building a system that uses multiple databases. I currently have a custom config file which I am using that has some controls in it. This file is not put through version control.
I would like these databases to be independant of git. I am looking to build a custom connection without using config/database.php
I could of course remove config/database.php from git but I want to keep it neat and make use of my custom config file.
Here is my clientconfig.php to be found in /config folder
<?php
$clientDB = '';
if(isset($_SERVER['SERVER_NAME'])) {
$apiDomain = $_SERVER['SERVER_NAME'];
if ( $apiDomain == 'www.example.com' ) {
$clientDB = 'clientdb_1';
}
}
return [
'client_db' => $clientDB
];
I would like to add my connections in that file too that are found in database.php
'connections' => [
'sqlite' => [
'driver' => 'sqlite',
'database' => env('DB_DATABASE', database_path('database.sqlite')),
'prefix' => '',
],
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'example'),
'username' => env('DB_USERNAME', 'example'),
'password' => env('DB_PASSWORD', 'example'),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'clientdb_1' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => ('clientdb_1'),
'username' => env('DB_USERNAME', 'example'),
'password' => env('DB_PASSWORD', 'example'),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
Is there a clean way this can be done?
EDIT: I have consired the .env file but it is too messy considering I may have different amount of databases etc. I will still be adding them to database.php which is what I am trying to avoid.
I was able to add my own new connection in that file by using config().
if ( $apiDomain == 'www.example.com' ) {
$appUrl = $apiDomain;
$clientDB = 'clientdb_1';
config(['database.connections.clientdb_1' => array(
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => $clientDB,
'username' => 'example',
'password' => 'example',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
)]);
}
NB: This did not work unless my custom config file was loaded after database.php. Because it was in alphabetical order I had to rename my file to z_clientconfig.php
I need to use several databases in laravel, and i'm trying to create a form to add a new db connection to connections array in config/database.php.
I don't want to add connections manually, but throught a form.
'connections' => [
'sqlite' => [
'driver' => 'sqlite',
'database' => env('DB_DATABASE', database_path('database.sqlite')),
'prefix' => '',
],
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'pgsql' => [
'driver' => 'pgsql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '5432'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'prefix' => '',
'schema' => 'public',
'sslmode' => 'prefer',
],
],
Thanks
You simple add as many databases to the array as you require then add the connection values to you .env file or to the array valyes like so:
return array(
'default' => 'my_first_db',
'connections' => array(
# Our primary database connection
'my_first_db' => array(
'driver' => 'mysql',
'host' => 'host1',
'database' => 'database1',
'username' => 'user1',
'password' => 'pass1'
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
# Our secondary database connection
'my_second_db' => array(
'driver' => 'mysql',
'host' => 'host2',
'database' => 'database2',
'username' => 'user2',
'password' => 'pass2'
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
),
);
Schema::connection('my_second_db')->create('a_new_table', function($table)
{
$table->increments('id'):
});
$users = DB::connection('my_second_db')->select('users');
To add connections through a form you would need to post the data to a template similar to the above and then write to the server, This is a bit of a security risk doing that and would need to be carefull in what you do and how you go about doing it, Posting database data in a request and then just saving the database data to a file is a bit overboard.
You could either setup a config file that has 10 databases pre-defined with PDO and then you could overwrite the settings or save to one of the config files that have no settings assigned.
You can use the config helper and set the config dynamically:
config([
'database.connections.mysql.database' => $dynamicDB,
'database.connections.mysql.username' => $dbUsername,
'database.connections.mysql.password' => $dbPassword,
// Any other dynamically set variables
]);
You could store the parameters in the session and default them to your config file:
config([
'database.connections.mysql.database' => session('db_database', config('database.connections.mysql.database')),
'database.connections.mysql.username' => session('db_username', config('database.connections.mysql.username')),
'database.connections.mysql.password' => session('db_password', config('database.connections.mysql.password')),
// Any other dynamically set variables
]);
Doing this in middleware would give you a little more control over where/when these parameters are being set and used.
Do i need to change database configuration in database.php file in laravel when upload to server?
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
Don't change anything in database.php config file. What you need to do is to change DB credentials in .env file on server side.
So, you'll have different .env files on a local machine and server, but the same database.php config file.
https://laravel.com/docs/5.3/configuration#environment-configuration
Update your database.php
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'yourdatabasename'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'password'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
I am trying to set a separate database for tests. For some reason when I run the migrations I have always a message saying: "Nothing to migrate."
Here is how I run the migrations:
php artisan migrate --database=mysql_test
Nothing to migrate.
And here is my config/database.php:
'default' => env('DB_CONNECTION', 'mysql'),
'connections' => [
'sqlite' => [
'driver' => 'sqlite',
'database' => env('DB_DATABASE', database_path('database.sqlite')),
'prefix' => '',
],
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'mydb'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'dev'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
'mysql_test' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'mydbtest'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'dev'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],
And obviously I can login to the database mydbtest with the credentials in the config.
Updating here after some troubleshooting:
After emptying mydb database and running the same command it filled the mydb database not mydbtest. This means it does not take into account what I am giving as database connection name.
Any suggestions to troubleshoot this are welcome.
Thanks
I found the problem.
After commenting out this line in my .env file it works now:
#DB_DATABASE=mydb
Thanks
