Notlar

Bilginize:

By contrast to the standard case folding functions such as strtolower() and strtoupper(), case folding is performed on the basis of the Unicode character properties. Thus the behaviour of this function is not affected by locale settings and it can convert any characters that have 'alphabetic' property, such a-umlaut (ä).

For more information about the Unicode properties, please see » http://www.unicode.org/reports/tr21/.

polyfill:

<?php
if(PHP_VERSION_ID < 80400) {
function
mb_ucfirst(string $str, string $encoding = null): string
{
if (
$encoding === null) {
$encoding = mb_internal_encoding();
}
return
mb_strtoupper(mb_substr($str, 0, 1, $encoding), $encoding) . mb_substr($str, 1, null, $encoding);
}

}
?>

if you wonder why i bother with mb_internal_encoding: prior to php7, $encoding was not nullable. if your polyfill don't need php5.6 support, you can drop it.
