Installtion

composer require nabeelalihashmi/LightDB

Basic Usage

LightDB::setConfig('testdb', 'root', '', 'localhost:3306');

// Insert 1 row
$country1 = [
    'country' => 'Pakistan',
    'capital' => 'Islamabad',
    'population' => 20000000
];
$id = LightDB::insert('south_asian_countries', $country1);

$result = LightDB::findById('south_asian_countries', 1);
$result = LightDB::find('south_asian_countries', 'country like ?', ['b%'], ['country', 'capital', 'population']);

Note

LightDB allows generation of query like


with following example

Update table set column = column + 1 where id = 1

to have such type of query, put .. and end of column name in key.

$item = LightDB::update('south_asian_countries', 'id = ? ', [1] , ['population..' => 'population + 1']);
