I have some questions. - Why need this function? Is not enough in array_filter or array_find? - In GitHub, There are many use cases in same name functions. from: https://github.com/search?q=array_match+language%3APHP&type=code - In past RFC in str_icontains https://wiki.php.net/rfc/str_icontains was declind. So I don't think make sense that "case-insensitive" only ASCII now. For your reference: In big OSS like php-src, We investigate use case first.
