Description:
------------
There is a difference in how sqlite_open and sqlite_popen handle relative filenames.

When I run a test-script (see below) from the base dir with:

./php -f sqlite_popen.php

all works fine, but when I place the exact same script in a sub-directory the difference becomes clear.

./php -f ext/dbx/tests/sqlite_popen.php

(this was tested on Win2k using cygwin)


Reproduce code:
---------------
<?php 
$database="ext/dbx/tests/dbx_test.sqlite.db";

$handle = sqlite_open($database);
var_dump($handle);
$handle = sqlite_popen($database);
var_dump($handle);

?>

Expected result:
----------------
resource(1) of type (sqlite database)
resource(2) of type (sqlite database (persistent))

Actual result:
--------------
PHP Warning:  sqlite_popen(): unable to open database: d:\...\ext\dbx\tests\ext\dbx\tests\dbx_test.sqlite.db in d:\...\ext\dbx\tests\sqlite_popen.php on line 6
resource(1) of type (sqlite database)
