Description

The following code:

#!/usr/bin/env php
<?php

print "open_basedir: ";
var_dump(ini_get("open_basedir"));
print "\n";

$db = new \PDO("sqlite::memory:?cache=shared", null, null, [
    \PDO::ATTR_PERSISTENT => true,
    \PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION,
    \PDO::ATTR_EMULATE_PREPARES => false,
    \PDO::ATTR_DEFAULT_FETCH_MODE => \PDO::FETCH_ASSOC,
]);

Resulted in this output:

$ ./sqlite-nomemory.php
open_basedir: string(0) ""

PHP Fatal error:  Uncaught PDOException: open_basedir prohibits opening :memory:?cache=shared in …\sqlite-nomemory.php:8
Stack trace:
#0 …\sqlite-nomemory.php(8): PDO->__construct('sqlite::memo
ry:...', NULL, Object(SensitiveParameterValue), Array)
#1 {main}
  thrown in …\sqlite-nomemory.php on line 8

But I expected this output instead:

I expected no error. Frankly, the code should just work.
