SQLite needs to create some temp-files (journals...) to execute certain statements, so php needs write-permission in your db-directory.

Actually, sqlite creates a journal-file when changing data and so it needs the write-permissions in the directory.

If you get the error message saying "SQLite3::exec. database locked." You just need to define a busyTimeout to work around this.

IMPORTANT! just a note:

weird behaviour when doing an exec on a sqlite db!!!

if want to execute a query on a sqlite db with exec, and your dbfile already was e.g. mode 777, and you get some php errors saying

"SQLite3::exec(): unable to open database file in ...."

and you get crazy while debugging, just add write ├╝ermissions to the whole directory for the user the webserver/php runs.

this behaviour makes absolutely NO sense, and is a source of frustration.
at least a more meaningful errormessage would be nice.
i couldnt figure out why sqlite needs write permissions for the whole dir instead of only one file. this is stupid and must be a bug!
(to be secure you have to create a directory with write permissions only for php/apache)
