(PHP 7, PHP 8)

IntlChar::totitle — Make Unicode character titlecase

Description

public static IntlChar::totitle(int|string $codepoint): int|string|null

The given character is mapped to its titlecase equivalent. If the character has no titlecase equivalent, the original character itself is returned.

Parameters

codepoint: The int codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")

Return Values

Returns the Simple_Titlecase_Mapping of the code point, if any; otherwise the code point itself. Returns null on failure.

The return type is int unless the code point was passed as a UTF-8 string, in which case a string is returned. Returns null on failure.

Examples

Example #1 Testing different code points

<?php
var_dump(IntlChar::totitle("Ǆ"));
var_dump(IntlChar::totitle("ǆ"));
var_dump(IntlChar::totitle("Φ"));
var_dump(IntlChar::totitle("φ"));
var_dump(IntlChar::totitle("1"));
var_dump(IntlChar::totitle("ᾳ");
var_dump(IntlChar::totitle(ord("A")));
?>

The above example will output:

string(1) "ǅ"
string(1) "ǅ"
string(2) "Φ"
string(2) "φ"
string(1) "1"
string(1) "ᾼ"
int(65)
