IntlChar::tolower

(PHP 7)
Make Unicode character lowercase
public static mixed IntlChar::tolower ( mixed $codepoint )

The given character is mapped to its lowercase equivalent. If the character has no lowercase 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_Lowercase_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::tolower("A"));
var_dump(IntlChar::tolower("a"));
var_dump(IntlChar::tolower("Φ"));
var_dump(IntlChar::tolower("φ"));
var_dump(IntlChar::tolower("1"));
var_dump(IntlChar::tolower(ord("A")));
var_dump(IntlChar::tolower(ord("a")));
?>

The above example will output:

string(1) "a"
string(1) "a"
string(2) "φ"
string(2) "φ"
string(1) "1"
int(97)
int(97)
