On the wiki on https://bitbucket.org/phpliteadmin/public/wiki/Installation
It tells you to install
"On Ubuntu/Debian Linux, you might do so using:
apt-get install php5-sqlite"
After trying for a few hours i could not get it to work, without a server.
"Package php5-sqlite is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source"
finally i found sudo apt-get install php7.0-sqlite3 once it was installed everything else worked. Someone should update the wiki to mention "sudo apt-get install php7.0-sqlite3"
