Installation

Read the INSTALL file, which comes with the package. Or just use the PEAR installer with pecl install sqlite. SQLite itself is already included, You do not need to install any additional software.

Windows users will enable php_sqlite.dll inside of php.ini in order to use these functions. The DLL for this PECL extension may be downloaded from either the » PHP Downloads page or from » http://pecl4win.php.net/

In PHP 5, the SQLite extension and the engine itself are bundled and compiled by default. However, since PHP 5.1.0 you need to manually activate the extension in php.ini (because it is now bundled as shared). Moreover, since PHP 5.1.0 SQLite depends on PDO it must be enabled too, by adding the following lines to php.ini (in order):

extension=php_pdo.dll
extension=php_sqlite.dll

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:

putenv('TMP=C:/temp');

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 schema - unable to open a temporary database file for storing temporary tables
