Definition

string to_titlecase(string $string, string $culture)

Converts $string to title case in a given $culture. The $culture defines the correct capital letter choice, rather than title capitalization rules.

Parameters

string $string

String to convert to title case.

string $culture

String defining the culture to correctly capitalize letters from other languages.

Returns

string

$string after capitalizing only the starting letter of each word, except the words completely in upper case, which are assumed to be acronyms and are therefore unchanged.
