IntlChar::tolower
(PHP 7)
IntlChar::tolower — Make Unicode character lowercase
Description
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 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_Lowercase_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
<?phpvar_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)
