This library provides an API for communicating with the HandlerSocket plugin for MySQL compatible databases(MySQL, MariaDB, Percona).
For more information on HandlerSocket, check out the MariaDB Documentation on HandlerSocket here.
Once you have composer installed, run the following in your php project directory:
composer require kornrunner/hsphp --no-update
$c = new \HSPHP\ReadSocket();
$c->connect();
$id = $c->getIndexId('data_base_name', 'table_name', '', 'id,name,some,thing,more');
$c->select($id, '=', array(42)); // SELECT WITH PRIMARY KEY
$response = $c->readResponse();
//SELECT with IN statement
$c = new \HSPHP\ReadSocket();
$c->connect();
$id = $c->getIndexId('data_base_name', 'table_name', '', 'id,name,some,thing,more');
$c->select($id, '=', array(0), 0, 0, array(1,42,3));
$response = $c->readResponse();$c = new \HSPHP\WriteSocket();
$c->connect('localhost',9999);
$id = $c->getIndexId('data_base_name','table_name','','k,v');
$c->update($id,'=',array(100500),array(100500,42)); // Update row(k,v) with id 100500 to k = 100500, v = 42
$response = $c->readResponse(); // Has 1 if OK$c = new \HSPHP\WriteSocket();
$c->connect('localhost',9999);
$id = $c->getIndexId('data_base_name','table_name','','k,v');
$c->update($id,'=',array(100500),array(100500,42), 2, 0, array(100501, 100502)); // Update rows where k IN (100501, 100502)
$response = $c->readResponse(); // Has 1 if OK$c = new \HSPHP\WriteSocket();
$c->connect('localhost',9999);
$id = $c->getIndexId('data_base_name','table_name','','k,v');
$c->delete($id,'=',array(100500));
$response = $c->readResponse(); //return 1 if OK$c = new \HSPHP\WriteSocket();
$c->connect('localhost',9999);
$id = $c->getIndexId('data_base_name','table_name','','k,v');
$c->insert($id,array(100500,'test\nvalue'));
$response = $c->readResponse(); //return array() if OK$c = new \HSPHP\WriteSocket();
$c->connect('localhost',9999);
$id = $c->getIndexId('data_base_name','table_name','','v');
$c->increment($id,'=',array(100500),array(2)); // Increment v column by 2

$id = $c->getIndexId('data_base_name','table_name','','v');
$c->decrement($id,'=',array(100500),array(2)); // Decrement v column by 2
$response = $c->readResponse(); // Has 1 if OK
