How to set lower text and first character as CAPS?

[toplisek]

I have code like:

foreach($var as $i=>$element) {
$var[$i] = ucfirst($element);
} 

Issue is that exploded text is all the time CAPS like
TEXT

When I try to ucfirst it will be not Text as all are CAPS.

PHP:
Returns a string with the first character of str capitalized, if that character is alphabetic.


If I try $var[$i] = mb_strtolower($element); it will be all lower.

How to set in one line mb_strtolower and the first character capitalized like Text?

$text = ucfirst(strtolower($text)); 

However, you might not like this if $text contains proper names which should be capitalized, or more than one sentence, or acronyms, or anything else that would require a capitalized letter in the middle of the string.

$text = ucfirst(strtolower($text)); 

I have tested many possibilities.

It works $var[$i] = mb_convert_case(mb_strtolower($element), MB_CASE_TITLE);

But still is issue UTF-8 encoding. How to work some special characters like č.
It shows me �

I worked some other function mb_strtolower($variable, 'UTF-8'))

How to set UTF-8 inside:
$var[$i] = mb_convert_case(mb_strtolower($element), MB_CASE_TITLE);
