Hello everone,

I'm having a really weird problem with SQLite when used with PHP - I'm pretty sure it's not SQLite that's at fault here, but since in the PHP-DB mailingliste nobody seemed to be able to help me, I'm hoping to get some insights here :-)

I'm trying to open an SQLite3 database from a PHP very simple PHP

$db = dirname(__FILE__).'/frontend.db';
$pdo = new PDO('sqlite:'.$db);
$pdo->query("SELECT * FROM page LIMIT 1");
echo "Deleting pages\n";
$pdo->query("DELETE FROM page");
echo "Deleting websites\n";
$pdo->query("DELETE FROM website");

The database file contains no data whatsoever, just the table
definitions (in case you were wondering, this is a stripped-down version
of a larger script for debugging purposes, hence the seemingly idiotic
DELETE statements that won't do any good in an empty database anyway,
but I digress...).

When executed on the command line, this works perfectly. When I execute
the same script via Apache and mod_php, I'm getting this exception:

PDOException: SQLSTATE[HY000]: General error: 1 SQL logic error or
missing database in /home/mwolff/webs/markus/cms/test.php on line 8

Getting experimental, I've tried to change the calls for the DELETE
statements from $pdo->query() to $pdo->exec(), just to see what happens.
Well, what happens is that I'm getting a different error:

PDOException: SQLSTATE[HY000]: General error: 14 unable to open database
file in /home/mwolff/webs/markus/cms/test.php on line 6

Argh... what can possibly be wrong here? The script works from the
commandline, with the exact same PHP version (Debian package, PHP
5.2.0-8+etch7, and we also tried upgrading to the latest Debian package
of 5.2.4, to no avail).

It can't be file permissions, I've even tried to set the database file
to 777... no change at all.

For the previous discussion in the PHP-DB mailinglist, see here (starting point, same content as above):

A detailed step-by-step list for reproducing the problem, including the used SQL schema, can be found here:

I hope someone here can point me in the right direction, I'm getting somewhat desperate :-)
