To create a SQLite in-memory database using PHP PDO, you must first and foremost provide the DSN (Data Source Name) to the PHP PDO object constructor as "
sqlite::memory", for example, like so:
Following that, you may use the PDO object as you normally would. For example, to create a table (with some initial dummy data), you could do the following:
$db = new PDO('sqlite::memory'); $schema =<<<SQL CREATE TABLE `customer` ( id INTEGER PRIMARY KEY AUTOINCREMENT, name VARCHAR(25) NOT NULL, date_birth DATE NOT NULL ); INSERT INTO customer(`name`, `date_birth`) VALUES ('John', '1978-01-01'), ('Wayne', '2015-08-01'); SQL; $db->exec($schema);
And to run queries after, you could, for example, do the following:
$sth = $db->prepare('SELECT * FROM `customer`'); $sth->execute(); $result = $sth->fetchAll(); var_dump($result); /* output: [ [ 'id' => 1, 'name' => 'John', 'date_birth' => '1978-01-01' ], [ 'id' => 2, 'name' => 'Wayne', 'date_birth' => '2015-08-01' ] ] */
