SQLite3::loadExtension — SQLite 拡張ライブラリを読み込む
name読み込みたいライブラリの名前。ライブラリは、設定オプション sqlite3.extension_dir で指定したディレクトリになければなりません。
例1 SQLite3::loadExtension() の例
<?php
$db = new SQLite3('mysqlitedb.db');
$db->loadExtension('libagg.so');
?>For newbies like me: if loadExtension fails with "Not supported in multithreaded Web servers" message (which always happens on IIS and sometimes - on Apache), you need to use non-thread-safe build of PHP, which is not always a bad idea; see https://www.geeksforgeeks.org/what-is-thread-safe-or-non-thread-safe-in-php/One more addition. If you need to setup non-thread-safe PHP on XAMPP/Apache to use loadextension, look at this article: https://paulshipley.id.au/blog/coding-tips/improve-php-performance-with-fastcgi-on-xampp-for-windows/
Tl;dr - you need to install&configure mod_fcgid module for Apache.
