The What
It’s available in PHP 4, 5, and 7.
Description
This construct converts a string’s alphabetic characters to lowercase. It uses the current locale to determine the converter. This function uses the Unicode character set for the character encoding.
Note: If you need to convert expanded character sets, such as umlaut-A (Ä), then use mb_strtolower() instead, as you can specify the character encoding, such as “UTF-8.”
Parameters

Return Values
This function returns the converted string.
