how to enable sqlite3 for php?

Edit: This answer is outdated, but can't be removed because it's accepted. Please see the solution from Stacey Richards for the correct answer.

 sudo apt-get install php5-cli php5-dev make
 sudo apt-get install libsqlite3-0 libsqlite3-dev
 sudo apt-get install php5-sqlite3
 sudo apt-get remove php5-sqlite3
 cd ~
 wget http://pecl.php.net/get/sqlite3-0.6.tgz
 tar -zxf sqlite3-0.6.tgz
 cd sqlite3-0.6/
 sudo phpize
 sudo ./configure
 sudo make
 sudo make install
 sudo apache2ctl restart

Ripped from the ubuntu form.

For PHP7, alter the below for your version of PHP (7.0, 7.2, 7.4, etc) and run

sudo apt-get install php7.0-sqlite3

and restart Apache

sudo apache2ctl restart

Try:

apt-get install php5-sqlite

That worked for me.
