If I use mysqli's prepared statements in an object and call
mysqli_stmt_bind_params, into which scope does mysqli_stmt_fetch()
place the variables? Can I control it? As of yet, I have no idea
where fetch() stores the results. It is fetching valid data. I'd
really like to use the OO style of MySQLi if possible. Any help or
guidance is greatly appreciated.
The offending code is as follows:
class StmtIterator {
private $data = 'test';
private $host = 'localhost';
private $user = 'root';
private $pass = '';
private $db; // Database connection
private $st; // Prepared statement
private $sql = "";
public function __construct ($sql, Array $params){
$this->db = mysqli_init();
$this->db->real_connect($this->host, $this->user, $this->pass, $this-
>data);
$this->sql = $sql;
$this->st = $this->db->stmt_init();
$this->st->prepare($this->sql);
$this->st->execute();
call_user_func_array(array($this->st, 'bind_result'), $params);
}
public function fetch (){
$result = $this->st->fetch();
if ($result !== true) echo "No data fetched.";
echo "Name is...<br /> ";
echo isset($this->st->name)
? "in this->st->name as {$this->st->name}.<br />"
: null;
echo isset($this->db->name)
? "in this->db->name as {$this->db->name}.<br />"
: null;
echo isset($this->params['name'])
? "in this->params['name'] as {$this->params['name']}.<br
/>"
: null;
echo isset($this->name)
? " this->name as {$this->name}.<br />"
: null;
echo isset($name)
? "in name as {$name}.<br />"
: null;
return $result;
}
public function __destruct (){
$this->st->close();
$this->db->close();
}
}
$sql = "
SELECT `id`, `name`
FROM `user`
WHERE 1
";
$params = array(
'id',
'name',
);
$user_iterator = new StmtIterator($sql, $params);
while ($user_iterator->fetch()){
echo isset($this->db->name)
? "in the local scope name as {$name}.<br />"
: null;
}
