I see everywhere (including on the official docs) that the PDO_SQLITE driver is/should be included by default in PHP.
However, when I look at my extension_directory, I see only these files:
gd.so mcrypt.so mysqli.so mysql.so pdo_mysql.so pdo.so
And, as a result, a framework I'm trying to install (Symfony) tells me I need to install either the PDO_SQLITE or the SQLite3 .so extensions...
Can anyone help? Can I just try and find the needed .so file somewhere on the web, place it in my extensions_directory and then include it in php.ini??
BTW: I'm running php 5.3.6 downloaded via apt-get on ubuntu.
did you try sudo apt-get install php5-sqlite?
For PHP 7.0 and greater:
sudo apt-get install php-sqlite3
For Windows users:
removed comment (;) from php.ini
extension=php_pdo_sqlite.dll
extension=php_sqlite3.dll
For Windows 10 - 64bits, version PHP 7.2 It's necessary remove only ( ; ) Before ;extension=pdo_sqlite ;extension=sqlite3
After extension=pdo_sqlite extension=sqlite3
Restart the server and already.
In my case i was using php 7.2 in Ubuntu. I had to run following command,
sudo apt install php7.2-sqlite
