It’s available in PHP 4, 5, and 7.
string strtolower( string $string_to_convert );
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.”
- This is the string to be converted into lowercase characters.
This function returns the converted string.
Hands off the keyboard. Web development starts by thinking first, then planning it out, and then coding it.
