PHP计数标题内的字符

I'm trying to count the text inside my title tag. But it doesn't seem to work. I've tried count(), strlen() etc. For example:

<title>Count me!</title>

When i use strlen() i get this error:

strlen() expects parameter 1 to be string, object given

When i use count u just get 2. I think it counts the title tags inside my file.

Controller:

$title = $dom->getElementsByTagName('title');
$count = strlen($title);

Index:

{{$count}}

    $title_tag = $dom->getElementsByTagName('title');
    foreach($tital_tag as $title){
    $title_length = strlen($title->nodeValue);
    }
    

    You need to loop through title tags ... It doesn't mean you have multiple tags . Dom simply return object which need to be accessed and then you get length of title
