Well the directory that houses the database should be writable. Running the script from command line it gives you write access probably but it won't work using mod_php because the web server probably can't write. Try it and give us some feedback.

Hey there,

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.

My guess is still permissions. If you try a raw fopen instead of using pdo, what happens?

ini_set('display_errors', true);
$fp = fopen(dirname(__FILE__).'/frontend.db', 'r');
if ($fp) {
  echo "Opened db<br/>\n";
} else {
  echo "Unable to open db<br/>\n";
