Snake Case
Snake case, also written snake_case is a way of writing names without spaces, where:
- All the letters are set to lower case
- Each word is separated from the other by an underscore
The underscore letters create humps like a camel’s back: this is the origin of the name.
Snake case is often used for PHP native functions.
<?php
function to_lower(string $string): int {
// PHP native function
return mb_strtolower($string);
}
?>
