The What
It’s available in PHP 4, 5, and 7.
Syntax
string mb_strtolower( string $string_to_convert, string $character_encoding = mb_internal_encoding() );
Description
This construct converts a string’s alphabetic characters to lowercase. It uses the current locale to determine the converter. Unlike the strtolower(), you can specify the character encoding, such as “UTF-8.”
Why? This function ensures characters such as umlaut-A (Ä) are properly converted.
Parameters
string_to_convert- This is the string to be converted into lowercase characters.
character_encoding- (optional) You can specify the character encoding to ensure that expanded character sets, such as umlaut-A (Ä) are properly converted.
Return Values
This function returns the converted string.
If you listen carefully, you can hear the 1s and 0s flowing in your computer.
