I've installed PHP 7.4.11 on macOS using Homebrew.
When I tried to enable extensions which are built with PHP, such as sqlite3 and pdo_sqlite, the extensions couldn't be found, as implied from the following warnings:
PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_sqlite' (tried: /usr/local/lib/php/pecl/20190902/pdo_sqlite (dlopen(/usr/local/lib/php/pecl/20190902/pdo_sqlite, 9): image not found), /usr/local/lib/php/pecl/20190902/pdo_sqlite.so (dlopen(/usr/local/lib/php/pecl/20190902/pdo_sqlite.so, 9): image not found)) in Unknown on line 0

In my extension's directory, /usr/local/lib/php/pecl/20190902/, there is not a single file. I expected shared object (.so) files for all the extensions built with PHP.
I also tried installing PHP 8.0 using the command brew install php --HEAD, but the problem persists. According to the Homebrew formula for PHP, all these extensions such as sqlite3, pdo_sqlite, etc should be built with PHP.
Can anyone tell me how I can resolve this issue?
