Manage your database with or without abstraction. This library is built on the PHP PDO plugin and is mainly used to build and execute SQL queries.
- PHP 8.0 and later.
- PHP PDO extension.
This library should work correctly in almost any database that uses basic SQL syntax. Databases supported by PDO and suitable drivers are available at https://www.php.net/manual/en/pdo.drivers.php.

}This library was developed with the thought that you would work with a single database and connection, but I know that in some projects you work with more than one connection and database.
If you want to work with a different non-global connection, use the connect() method.
use \InitPHP\Database\DB;
DB::connect([
'dsn' => 'mysql:host=localhost;port=3306;dbname=test;charset=utf8mb4',
'username' => 'root',
'password' => '',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_general_ci',
]);Model and Entity; are two common concepts used in database abstraction. To explain these two concepts in the roughest way;
- Model : Each model is a class that represents a table in the database.
- Entity : Entity is a class that represents a single row of data.
The most basic example of a model class would look like this.
namespace App\Model;
class Posts extends \InitPHP\Database\Model
{
/**
* If your model will use a connection other than your global connection, provide connection information.
* @var array|null <p>Default : NULL</p>
*/
protected array $credentials = [
'dsn' => '',
'username' => 'root',
'password' => '',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
];
/**
* If not specified, \InitPHP\Database\Entity::class is used by default.
*
* @var string<\InitPHP\Database\Entity>
*/
protected $entity = \App\Entities\PostEntity::class;
/**
* If not specified, the name of your model class is used.
*
* @var string
*/
protected string $schema = 'posts';
/**
* The name of the PRIMARY KEY column. If not, define it as NULL.
*
* @var string
*/
protected string $schemaId = 'id';
/**
* Specify FALSE if you want the data to be permanently deleted.
*
* @var bool
*/
protected bool $useSoftDeletes = true;
/**
* Column name to hold the creation time of the data.
*
* @var string|null
*/
protected ?string $createdField = 'created_at';
/**
* The column name to hold the last time the data was updated.
*
* @var string|null
*/
protected ?string $updatedField = 'updated_at';
/**
* Column name to keep deletion time if $useSoftDeletes is active.
*
* @var string|null
*/
protected ?string $deletedField = 'deleted_at';
protected bool $readable = true;
protected bool $writable = true;
protected bool $deletable = true;
protected bool $updatable = true;
}The most basic example of a entity class would look like this.
namespace App\Entities;
class PostEntity extends \InitPHP\Database\Entity
{
/**
* An example of a getter method for the "post_title" column.
*
* Usage :
* echo $entity->post_title;
*/
public function getPostTitleAttribute($title)
{
return strtoupper($title);
}
/**
* An example of a setter method for the "post_title" column.
*
* Usage :
* $entity->post_title = 'New Post Title';
*/
public function setPostTitleAttribute($title)
{
$this->post_title = strtolower($title);
}
}Below I have mentioned some developer tools that you can use during and after development.
use \InitPHP\Database\DB;
DB::createImmutable([
'dsn' => 'mysql:host=localhost;dbname=test;port=3306;charset=utf8mb4;',
'username' => 'root',
'password' => '',
'log' => __DIR__ '/logs/db.log', // string, callable or object
]);If you define a file path as a String; Attempts are made to write into it with file_put_contents().
Note : You can define variables such as {year}, {month}, {day} in the filename.
- You can also define an object with the
criticalmethod. The database library will pass the log message to this method as a parameter. Or define it as callable array to use any method of the object.
use \InitPHP\Database\DB;
class Logger {
public function critical(string $msg)
{
$path = __DIR__ . '/log.log';
file_put_contents($path, $msg, FILE_APPEND);
}
}
$logger = new Logger();
DB::createImmutable([
'dsn' => 'mysql:host=localhost;dbname=test;port=3306;charset=utf8mb4;',
'username' => 'root',
'password' => '',
'log' => $logger, // or [$logger, 'critical']
]);- Similarly it is possible to define it in a callable method.
use \InitPHP\Database\DB;
DB::createImmutable([
'dsn' => 'mysql:host=localhost;dbname=test;port=3306;charset=utf8mb4;',
'username' => 'root',
'password' => '',
'log' => function (string $msg) {
$path = __DIR__ . '/log.log';
file_put_contents($path, $msg, FILE_APPEND);
},
]);Debug mode is used to include the executed SQL statement in the error message. It should only be activated in the development environment.
use \InitPHP\Database\DB;
DB::createImmutable([
'dsn' => 'mysql:host=localhost;dbname=test;port=3306;charset=utf8mb4;',
'username' => 'root',
'password' => '',
'debug' => true, // boolean
]);Profiler mode is a developer tool available in v3 and above. It is a feature that allows you to see the executed queries along with their execution times.
use InitPHP\Database\DB;
DB::enableQueryLog();
DB::table('users')->where('name', 'John')->read();
var_dump(DB::getQueryLogs());
/**
* The output of the above example looks like this;
* [
* [
* 'query' => 'SELECT * FROM users WHERE name = :name',
* 'time' => '0.00064',
* 'args' => [
* ':name' => 'John',
* ]
* ]
* ]
*
