I want to create a simple website on elgg.org and one of its requirements is to install PHP. I have almost zero experience in coding.
PHP 7.2+ with the following extensions:
GD (for graphics processing)
PDO (for database connection)
JSON (for AJAX responses, etc.)
XML (for reading plugin manifest files, etc.)
Multibyte String support (for i18n)
Proper configuration and ability to send email through an MTA
What should I download and what should I do with these extensions?
