Usage

<?php

require_once 'cyrillic-check.php';

$text = 'Привет, мир!'; // This is a Cyrillic text
$containsCyrillic = is_cyrillic($text);

if ($containsCyrillic) {
    echo "The text contains Cyrillic characters";
} else {
    echo "The text doesn't contain Cyrillic characters";
}

?>

Result

The result of the above code will be:

The text contains Cyrillic characters

How it works

The is_cyrillic function uses the regular expression /[\p{Cyrillic}]/u to match any Cyrillic character present in the text. The u modifier is used to indicate that the regular expression should be treated as Unicode.
