PHP Convert string to UTF code?

Question

PHP

I need to convert the string to this form:

Please help :)

Answer 1

function convert($str) {
    $str = mb_convert_encoding($str , 'UTF-32', 'UTF-8'); // Big endian
    $t = unpack('N*', $str);
    $t = array_map(function($n) { return "&#$n;"; }, $t);

    return join('', $t);
}

var_dump(convert('foo bar')); // string(39) "foo bar"

If you need a unicode sequence - see this question on stackoverflow and apply the reverse transformation.
