The SQLite3 extension is enabled by default as of PHP 5.3.0. It's
possible to disable it by using --without-sqlite3
at compile time.
Windows users must enable php_sqlite3.dll in order to use this extension. This DLL is included with Windows distributions of PHP as of PHP 5.3.0.
Note: Additional setup on Windows as of PHP 7.4.0
In order for this extension to work, there are DLL files that must be available to the Windows system PATH. For information on how to do this, see the FAQ entitled "How do I add my PHP directory to the PATH on Windows". Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the system's PATH), this is not recommended. This extension requires the following files to be in the PATH: libsqlite3.dll.
Note:
This extension was briefly a PECL extension but that version is only recommended for experimental use.
