Question

Basically I have this string for example $str = 'По, своей 12' I need something that returns the numbers of chars and numbers (leaving off spaces and other punctuation)

How can I achive this? Maybe doing a preg_replace with \p{L} and [0-9] ?

countChars('По, своей 12'); //> Should return: 9

Note: mb_strlen() counts spaces and punctuation too and i don’t want this

Answer 1

I did it:

function countChars($haystack) {

    $count = preg_replace("/[^\p{L}0-9]/uim",'',$haystack);
    return mb_strlen($count);

}
