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.

The best way to install Dibi is to use a Composer:

php composer.phar require dibi/dibi

Or you can download the latest package from http://dibiphp.com. In this package is also Dibi.minified, shrinked single-file version of whole Dibi, useful when you don't want to modify library, but just use it.

Dibi requires PHP 5.2.0 or later. It has been tested with PHP 5.5 too.

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(array(
    '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 = array(
    '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', array(
	'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(
	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', array(
    '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;
