Introduction
------------
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.
If you like Dibi, **[please make a donation now](https://nette.org/make-donation?to=dibi)**. Thank you!
Installation
------------
The recommended way to install Dibi is via Composer (alternatively you can [download package](https://github.com/dg/dibi/releases)):
```bash
composer require dibi/dibi
```
The Dibi 3.x requires PHP version 5.4.4 and supports PHP up to 7.2.
Usage
-----
Refer to the `examples` directory for examples. Dibi documentation is
available on the [homepage](https://dibiphp.com).
Connect to database:
```php
$dibi = new Dibi\Connection([
'driver' => 'mysqli',
'host' => 'localhost',
'username' => 'root',
'password' => '***',
]);
// or static way; in all other examples use dibi:: instead of $dibi->
dibi::connect($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)
```
%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
```php
$dibi->query("SELECT * FROM table WHERE name LIKE %like~", $query);
```
%like~ | begins with |
%~like | ends with |
%~like~ | contains |
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;
```
