IntlChar::toupper — Make Unicode character uppercase
Description
public static mixed IntlChar::toupper ( mixed $codepoint )
The given character is mapped to its uppercase equivalent. If the character has no uppercase equivalent, the 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}")
Return Values
Returns the Simple_Uppercase_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
Example #1 Testing different code points
<?php
var_dump(IntlChar::toupper("A")
var_dump(IntlChar::toupper("a")
var_dump(IntlChar::toupper("Φ")
var_dump(IntlChar::toupper("φ")
var_dump(IntlChar::toupper("1")
var_dump(IntlChar::toupper(ord("A"))
var_dump(IntlChar::toupper(ord("a"))
?>

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