IntlChar::totitle

(PHP 7)

Make Unicode character titlecase

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

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

Returns:

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

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

Examples:

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)
