Data Access Object

Data Access Object is tiny wrapper on php PDO. There was add more comfortable methods usage conditions in select query.

PDO Usage

<?php
$db = new PDO(
    $GLOBALS['config']['db']['dsn'],
    $GLOBALS['config']['db']['user'],
    $GLOBALS['config']['db']['pass']
);
$db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC); 
$db->setAttribute(PDO::ATTR_ORACLE_NULLS, PDO::NULL_EMPTY_STRING); 
$db->setAttribute(PDO::ATTR_CASE, PDO::CASE_NATURAL); 


$res = $db->query('SET NAMES utf8mb4');

if (!$res) {
    throw new Exception('Database connection error);
}

$db = DataAccessObject::factory($db);

Search

$search = [
       'columnName'     => 5,
       'columnName2&IN' => [1, 2, 3, 4]
       'columnName3&<'  => 7,
       'columnName4&>=' => 3
     ];

$sql = "SELECT * FROM users";
$db->select($sql, $search, [], DataAccessObjectInterface::FETCH_ALL)->toNative();

Conditions

key	value	result
-	'column = 5'	column = 5
col&<action>	'item'	col <action> 'item'
column	5	column = '5'
column	null	column IS NULL
column&IN	'val1, val2, val3'	column IN ('val1', 'val2', 'val3')
column&IN	array('val1', 'val2', 'val3')	column IN ('val1', 'val2', 'val3')
column&NOT IN	'val1, val2, val3'	column NOT IN ('val1', 'val2', 'val3')
column&NOT IN	array('val1', 'val2', 'val3')	column NOT IN ('val1', 'val2', 'val3')
sql_or	array('col1 = 5', 'col2 = 8')	((col1 = 5 ) OR (col2 = 8))
sql_or	array(array('col1' => 5), array('col2' => 8, 'col3' => 7))	((col1 = 5) OR (col2 = 8 AND col3 = 7))
sql_and	array('col1 = 5', 'col2 = 8')	col1 = 5 AND col2 = 8
sql_and	array(array('col1' => 5), array('col2' => 8, 'col3' => 7))	col1 = 5 AND col2 = 8 AND col3 = 7
something&or_sql	array('col1 = 5', 'col2 = 8')	(col1 = 5 OR col2 = 8)
col&or	array('val1', array('col2' => 5, 'col3' => 8))	(col = 'val1' OR col2 = '5' OR col3 = '8')
col&or&>=	array(7, array('col2' => 5, 'col3' => 8))	(col >= 7 OR col2 = '5' OR col3 = '8')
col&match	'something'	MATCH (col) AGAINST ('something')
col&between	array(3)	"col" >= '3'
col&between	array(1 => 7)	"col" <= '7'
col&between	array(3, 7)	"col" BETWEEN '3' AND '7'
col&between	'3 AND 7'	"col" BETWEEN 3 AND 7
col&soundex	'val1'	SOUNDEX(col) = SOUNDEX('val1')
