PHP Variable Variables

Answer 1

Use var_dump?

Answer 2

current/next is painful, and I'm not sure what's with the {} dereferencing.

Why not just:

$resc = $db->query("SELECT * FROM blog_comments WHERE id='$id' LIMIT 1");

while($row = $db->fetch_assoc($resc)) {
    foreach($row as $key=>$value){
       $this->$key = $value;
    }
}

Answer 3

You want

$comment[$key]

$comment{$key} will give you the nth character of a string. Since $key itself is a string, PHP converts that to an integer 0 and you get the first char.

Answer 4

I think you need to change this line:

$this->$key = $comment{$key};

with:

$this->$key = $comment[$key];
