In PHP, how do I sort strings with built-in functions?

In PHP, you can sort strings using various built-in functions. One of the most commonly used functions for sorting arrays of strings is `sort()`. This function sorts an array in ascending order. If you want to sort strings in a case-insensitive manner, you can use `usort()` with a user-defined comparison function or `asort()` for associative arrays while maintaining key-value associations.
