What are the potential pitfalls of using strtolower() in PHP to convert text to lowercase?
Using strtolower() in PHP to convert text to lowercase can potentially lead to issues with certain non-English characters or special symbols that may not be handled correctly. To ensure proper lowercase conversion for all characters, it is recommended to use mb_strtolower() instead, which supports multi-byte character encoding.
$text = "Hello World!";
$lowercaseText = mb_strtolower($text);
echo $lowercaseText;
