I've looked around and found two >SQLite-related files: php_pdo_sqlite.dll and php_sqlite3.dll, both are >around 840 kB. There is no DLL named like json1. Intriguing issue. Could you try the json1.dll inside https://phpdev.toolsforresearch.com/php-7.3.2-nts-Win32-VC15-x64.zip See https://www.apachelounge.com/viewtopic.php?t=6359 for info about these builds. Note: sqlite3.extension_dir in your php.ini should contain the full path to the directory with the json1.dll. I tested loading of the extension with the following php.ini: sqlite3.extension_dir = "N:\php-sdk\php73dev\x64\Release\php-7.3.2" extension_dir = "ext" extension=sqlite3 The json1.dll should also work with your XAMPP, AFAIK. -- Jan
