Not quite. If the database name is an empty string, a private, temporary on-disk database is created. However, you're right that this has to be properly documented.

This will result in a in-memory database. In previous versions of PHP7 (I tested this with v7.0.2) this would have resulted in a exception. The documentation is not mentioning this feature. Test script: --------------- The unit test below works in v7.0.2, but fails in v7.0.17 class SQLiteConstructorTest extends PHPUnit_Framework_TestCase { /** * @expectedException Exception */ public function testDefectDatabaseFile() { $database_file = ''; $sqlitedb = new SQLite3($database_file); } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74397&edit=1
