dibi - smart database abstraction layer

Dibi - smart database layer for PHP

Database access functions in PHP are not standardised. This library hides the differences between them, and above all, it gives you a very handy interface.

Installation

The best way how to install Dibi is to download a latest package or use a Composer:

composer require dibi/dibi

The Dibi 3 requires PHP version 5.4.4 or newer (is compatible with PHP 7.0 and 7.1), version 4 requires PHP 7.1.

Examples

Refer to the examples directory for examples. Dibi documentation is available on the homepage.

Connect to database:

// connect to database (static way)
dibi::connect([
    'driver'   => 'mysql',
    'host'     => 'localhost',
    'username' => 'root',
    'password' => '***',
]);

// or object way; in all other examples use $connection-> instead of dibi::
$connection = new DibiConnection($options);

SELECT, INSERT, UPDATE

dibi::query('SELECT * FROM users WHERE id = ?', $id);

$arr = [
    'name' => 'John',
    'is_admin'  => true,
];
dibi::query('INSERT INTO users', $arr);
// INSERT INTO users (`name`, `is_admin`) VALUES ('John', 1)

dibi::query('UPDATE users SET', $arr, 'WHERE `id`=?', $x);
// UPDATE users SET `name`='John', `is_admin`=1 WHERE `id` = 123

dibi::query('UPDATE users SET', [
	'title' => array('SHA1(?)', 'tajneheslo'),
]);
// UPDATE users SET 'title' = SHA1('tajneheslo')

Getting results

$result = dibi::query('SELECT * FROM users');

$value = $result->fetchSingle(); // single value
$all = $result->fetchAll(); // all rows
$assoc = $result->fetchAssoc('id'); // all rows as associative array
$pairs = $result->fetchPairs('customerID', 'name'); // all rows as key => value pairs

// iterating
foreach ($result as $n => $row) {
    print_r($row);
}

Modifiers for arrays:

dibi::query('SELECT * FROM users WHERE %and', [
	array('number > ?', 10),
	array('number < ?', 100),
]);
// SELECT * FROM users WHERE (number > 10) AND (number < 100)

%and		`[key]=val AND [key2]="val2" AND ...`
%or		`[key]=val OR [key2]="val2" OR ...`
%a	assoc	`[key]=val, [key2]="val2", ...`
%l %in	list	`(val, "val2", ...)`
%v	values	`([key], [key2], ...) VALUES (val, "val2", ...)`
%m	multivalues	`([key], [key2], ...) VALUES (val, "val2", ...), (val, "val2", ...), ...`
%by	ordering	`[key] ASC, [key2] DESC ...`
%n	identifiers	`[key], [key2] AS alias, ...`
other	-	`val, val2, ...`

Modifiers for LIKE

dibi::query("SELECT * FROM table WHERE name LIKE %like~", $query);

%like~	begins with
%~like	ends with
%~like~	contains

DateTime:

dibi::query('UPDATE users SET', [
    'time' => new DateTime,
]);
// UPDATE users SET ('2008-01-01 01:08:10')

Testing:

echo dibi::$sql; // last SQL query
echo dibi::$elapsedTime;
echo dibi::$numOfQueries;
echo dibi::$totalTime;
