How to make an pdo_sqlite connection from binary stream in PHP

Question

Having a .sqlite file in a memory stream (php://memory), I want to pipe it to pdo_sqlite driver to create a connection. Is this possible?

Its for testing purposes, I want to recreate DBs quickly without recreate schema at each time nor using tmpfs.

Answer 1

In memory sqlite has some limitations. The memory space could be the request, the session, but no way seems documented to share a base in memory among users.

For a request, open your base with the code

$pdo = new PDO( 'sqlite::memory:'); 

and your base will disapear on next request.

For session persistency

<?php 
$pdo = new PDO( 
    'sqlite::memory:', 
    null, 
    null, 
    array(PDO::ATTR_PERSISTENT => true) 
); 
?>
