A very light-weight and simple ORM-like MySQL library for PHP. Kind of like ActiveRecord's little brother.

# initialize and connect to database
$sql = new litemysql('host', 'username', 'password', 'database', 'table', 'encoding');

# fetch all rows
$rows = $sql->find_all();

# insert a single row
$sql->insert(array('title' => 'hello', 'body' => 'Dude, sweet!', 'author' => 'John Doe'));

# fetch last inserted row
$sql->find($sql->last_insert_id);

You can place all your MySQL settings in a file like config.php bellow:

<?php
$database_settings = array(
	'host' => 'localhost',
	'username' => 'user',
	'password' => 'pass',
	'database' => 'database',
	'table' => 'table',
	'encoding' => 'utf8',
	'primary_key' => 'user_id',
	'persistent' => false,
);
?>

Then use the config file:

$sql = new litemysql('config.php');

And you can also override any option specified in the config file:

$sql = new litemysql('config.php', null, null, 'my_database', 'my_table');

Conditions can be specified in three ways:

• As an integer, which is used as the primary_key value to find a single row.
• As an array, which uses the array keys as columns and array values as column values.
  • If one of the values in the array, is an array itself, the value is specified using IN in the SQL query.
• As a string, which is used as a custom raw SQL where statement. Use with care as it's not filtered for possible SQL injections.

$result = $sql->find( 3 );
$result = $sql->find( array('id' => 3) );
$result = $sql->find( '`id` = 3' );
$result = $sql->find_all( array('id' => array(1,3,5)) );

Using the $options argument, you can specify LIMIT, OFFSET, ORDER BY, and GROUP BY options for the query. They key names used in the array are limit, offset, order, and group.

$result = $sql->find_all(null, array('order' => 'title'));

Retrieves a single record matching $conditions, or false if no record is found.

Works just like find(), but retrieves all matching rows. Can be limited with the limit option. Returns an empty array if no records matched the specified conditions.

Takes an array as input. To insert a single record, the array should have keys matching the columns. To insert multiple records, $input must be an array with arrays containing column keys.

Insert a single record:

$sql->insert(
   array(
      'title' => 'hello world',
      'body' => 'my first blog post :D',
      'author' => 'John Doe'
   )
);

Insert multiple records:

$sql->insert(
	array(
		array(
			'title' => 'hello world',
			'body' => 'my first blog post :D',
			'author' => 'John Doe',
		),
		array(
			'title' => 'omg omg!',
			'body' => 'i r uber cool!',
			'author' => 'Rupert McIdiot',
		),
	)
);

Updates a single record matching $conditions, with the same input format as insert() takes for a single record insert.

$sql->update(4, array('author' => 'James Dole'));

Works just like update(), but it updates all records matching $conditions.

Change author "John Doe" to "John Smith".

$sql->update_all(array('author' => 'John Doe'), array('author' => 'John Smith'));

Deletes a single record matching $conditions.

$sql->delete(4);

Deletes all records matching $conditions.

$sql->delete_all(array('author' => 'John Smith'));

Counts how many records match $conditions.

$result = $sql->count(array('author' => 'John Smith'));

Fetches X number of records from table sorted by random matching $conditions. Use $limit to specify how many records to retrieve. Be warned that this method uses ORDER BY RAND() which can be very slow on large tables.

Increment a integer column by $count on a single record matching $conditions. $count defaults to 1 if not specified.

To decrement instead of increment, simply specify a negative $count value.

$sql->increment(array('slug' => 'hello-world'), 'views');

Perform a SQL query.

Performs an OPTIMIZE query on the current table.

Truncates the table if $are_you_sure is true. WARNING: This removes ALL records from the current table.

Change the default column name used by the condition builder.

$sql->primary_key = 'user_id';
$result = $sql->find(3);

This creates a user_id = 3 WHERE clause in the query instead of the default id = 3.

Contains the primary_key value of the last inserted record.

$sql->last_insert_id;

If $sql->enable_logging is set to true, all queries are logged to $sql->query_log.

• Create some kind of basic tests for all the features.
• Restructure and rewrite this ReadMe so it doesn't suck.
• Come up with more to-do's for this list.
