Question

i have this function

protected function insert($data){
        $data['datecreated'] = date('Y-m-d h:i:s');
        echo "array_keys(data) = ".$data['datecreated'];
        var_dump($data);
        echo array_keys($data);
        $sql = "INSERT INTO {$this->table_name} (".  array_keys($data).")"; 
        $sql.= " VALUES ('";
        $sql.=implode("','", $data);
        $sql.=")";
        $this->execute($sql);
        $this->last_id = mysql_insert_id();
    }

when i read the array_keys($data) it returns ‘Array’ not the key
i call it like this $this->insert(array()); why is that ?
EDIT :
this is the output

array_keys(data) = 2012-05-18 04:44:46array(2) { [0]=> array(0) { } ["datecreated"]=> string(19) "2012-05-18 04:44:46" } Array

Answer 1

array_keys returns an array with all the keys.
You need to implode that aswell

implode(',', array_keys($data));

Edit:
And you might want to take a look at this part

$sql.=implode("','", $data);
$sql.=")";

You need need a starting and trailing '.
