PHP install sqlite3 extension

Question

We are using PHP 5.3.6 here, but we used the --without-sqlite3 command when compiling PHP. (It stands in the 'Configure Command' column). But, it is very risky to recompile PHP on that server; there are many visitors. How can we install/use sqlite3?

In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Answer 1

install php without it and then install the package: php5-sqlite3 then restart apache to make it work.

Answer 2

but we used the --without-sqlite3 command when compiling PHP. (It stands in the 'Configure Command' column)

No. You didn't specify. It's the default option when installing binary package.

But, it is very risky to recompile PHP on that server; there are many visitors.

--without-xx from the Configure Command column in the phpinfo() page doesn't mean you have to recompile PHP to enable. For example, you can see --without-mysql option but you still can install php-mysql to enable it:

mysql

MySQL Support => enabled
Active Persistent Links => 0
Active Links => 0
Client API version => 5.5.15
MYSQL_MODULE_TYPE => external
MYSQL_SOCKET => /var/lib/mysql/mysql.sock
MYSQL_INCLUDE => -I/usr/include/mysql
MYSQL_LIBS => -L/usr/lib64/mysql -lmysqlclient 

Since you installed php-pdo package:

/etc/php.d/pdo_sqlite.ini,
PDO drivers => mysql, sqlite
pdo_sqlite
PDO Driver for SQLite 3.x => enabled
SQLite Library => 3.3.6

The sqlite3 extension is already enabled, but in the different name pdo_sqlite. Just use it to access to the SQLite 3 database.
