Since PHP 5.0 this extension was bundled with PHP.
Beginning with PHP 5.4, this extension is available only via
Windows users must enable php_sqlite.dll inside of php.ini in order to use these functions. A
DLL for this
is currently unavailable. See also the building on Windows section.
Windows builds must also enable PDO because as of
PHP 5.1.0 it depends on it. So, php.ini
will end up with something like this:
On Linux or Unix operating systems, if you build PDO as a shared
extension, you must build SQLite as a shared extension using the
The PHP 5.0.x series of Windows builds enabled this
extension by default, where no DLL file is necessary.
SQLite 3 is supported through PDO SQLite.
Note: Windows installation
for unprivileged accounts
On Windows operating systems, unprivileged accounts
don’t have the TMP environment variable set by default. This
will make sqlite create temporary files in the windows directory,
which is not desirable. So, you should set the TMP environment variable
for the web server or the user account the web server is running
under. If Apache is your web server, you can accomplish this via a
SetEnv directive in your
httpd.conf file. For example:SetEnv TMP c:/temp
If you are unable to establish this setting at the server level,
you can implement the setting in your script:
The setting must refer to a directory that the web server has
permission to create files in and subsequently write to and delete
the files it created. Otherwise, you may receive the following
error message: malformed database
