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.
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;
