本文介绍了一种在使用PHP执行SQLite数据库操作时遇到的奇怪行为。当尝试使用exec执行查询时，即使数据库文件已设置为可读写，仍可能会收到无法打开数据库文件的错误。解决方法是确保数据库文件及其所在目录对于Web服务器/PHP运行的用户具有写权限。

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 üermissions 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)
