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](https://github.com/dg/dibi/releases) or use a Composer:

```bash
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](https://dibiphp.com).

Connect to database:

```php
// 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

```php
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

```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('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', [
    '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;
```
