IntlChar::totitle

(PHP 7, PHP 8)

IntlChar::totitle — Make Unicode character titlecase

Description

public static IntlChar::totitle(mixed $codepoint): mixed

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.

The return type will be int unless the code point was passed as a UTF-8 string, in which case a string will be returned.

Examples

Example #1 Testing different code points

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

The above example will output:

string(1) "A"
string(1) "A"
string(2) "Φ"
string(2) "Φ"
string(1) "1"
int(65)
int(65)
