nl_langinfo()
nl_langinfo() is a PHP topic. In plain words you use it for a short nl_langinfo example in a college portal page. Don’t start with a slogan — start with that picture.
Smallest example: the smallest nl_langinfo example you can type. Type it, run it, and say what you see. If you can do that from memory, you know nl_langinfo().
From the example next to this theory — nl_langinfo(): scores array, print avg, then high marks.
Trap — only saying “nl_langinfo” with no example. Fix that before you talk about advanced PHP.
