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](http://getcomposer.org/download):

    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 the 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](http://dibiphp.com).

Connect to database:

```php
// 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

```php
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

```php
$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:

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

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


Modifiers for LIKE

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

<table>
<tr><td> %like~	</td><td> begins with </td></tr>
<tr><td> %~like	</td><td> ends with </td></tr>
<tr><td> %~like~ </td><td> contains </td></tr>
</table>

DateTime:

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

Testing:

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