Installation

========

When you're ready to get started, see the [Quick Start Guide](http://www.meekro.com/quickstart.php) on our website.



### Manual Setup

Include the `db.class.php` file into your project and set it up like this:



```php

require_once 'db.class.php';

DB::$user = 'my_database_user';

DB::$password = 'my_database_password';

DB::$dbName = 'my_database_name';

```



### Composer

Add this to your `composer.json`



```json

{

  "require": {

    "sergeytsalkov/meekrodb": "*"

  }

}

```



Code Examples

========

### Grab some rows from the database and print out a field from each row.



```php

$accounts = DB::query("SELECT * FROM accounts WHERE type = %s AND age > %i", $type, 15);

foreach ($accounts as $account) {

  echo $account['username'] . "\n";

}

```



### Insert a new row.



```php

DB::insert('mytable', array(

  'name' => $name,

  'rank' => $rank,

  'location' => $location,

  'age' => $age,

  'intelligence' => $intelligence

));

```

    

### Grab one row or field



```php

$account = DB::queryFirstRow("SELECT * FROM accounts WHERE username=%s", 'Joe');

$number_accounts = DB::queryFirstField("SELECT COUNT(*) FROM accounts");

```



### Use a list in a query

```php

DB::query("SELECT * FROM tbl WHERE name IN %ls AND age NOT IN %li", array('John', 'Bob'), array(12, 15));

```



### Log all queries and errors

```php

// log all queries and errors to file, or ..

DB::$logfile = '/home/username/logfile.txt';



// log all queries and errors to screen

DB::$logfile = fopen('php://output', 'w');

```



### Nested Transactions

```php

DB::$nested_transactions = true;

DB::startTransaction(); // outer transaction

// .. some queries..

$depth = DB::startTransaction(); // inner transaction

echo $depth . 'transactions are currently active'; // 2

 

// .. some queries..

DB::commit(); // commit inner transaction

// .. some queries..

DB::commit(); // commit outer transaction

```

How is MeekroDB better than PDO?

========

### Optional Static Class Mode

Most web apps will only ever talk to one database. This means that 

passing $db objects to every function of your code just adds unnecessary clutter. 

The simplest approach is to use static methods such as DB::query(), and that's how 

MeekroDB works. Still, if you need database objects, MeekroDB can do that too.



### Do more with fewer lines of code

The code below escapes your parameters for safety, runs the query, and grabs 

the first row of results. Try doing that in one line with PDO.



```php

$account = DB::queryFirstRow("SELECT * FROM accounts WHERE username=%s", 'Joe');

```



Or how about just one field?



```php

$created_at = DB::queryFirstField("SELECT created_at FROM accounts WHERE username=%s", 'Joe');

```



### Work with list parameters easily

Using MySQL's IN keyword should not be hard. MeekroDB smooths out the syntax for you, 

PDO does not.



```php

$accounts = DB::query("SELECT * FROM accounts WHERE username IN %ls", array('Joe', 'Frank'));

```



### Simple inserts

Using MySQL's INSERT should not be more complicated than passing in an 

associative array. MeekroDB also simplifies many related commands, including 

the useful and bizarre INSERT .. ON DUPLICATE UPDATE command. PDO does none of this.



```php

DB::insert('accounts', array('username' => 'John', 'password' => 'whatever'));

```



### Nested transactions

MySQL's SAVEPOINT commands lets you create nested transactions, but only 

if you keep track of SAVEPOINT ids yourself. MeekroDB does this for you, 

so you can have nested transactions with no complexity or learning curve.



```php

DB::$nested_transactions = true;

DB::startTransaction(); // outer transaction

// .. some queries..

$depth = DB::startTransaction(); // inner transaction

echo $depth . 'transactions are currently active'; // 2

 

// .. some queries..

DB::commit(); // commit inner transaction

// .. some queries..

DB::commit(); // commit outer transaction

```



### Flexible debug logging and error handling

You can log all queries (and any errors they produce) to a file for debugging purposes. You can also add hooks that let you run your own functions at any point in the query handling process.
