Question

Is it possible to ask for all data in my database and make objects from it and save it into an array or something, so I just need to call the database once and afterwards I just use my local array? If yes, how is it done?

public function getAllProjects(){

   $query="SELECT * FROM projects";
   $result=mysql_query($query);
   $num=mysql_numrows($result);
   while ($row = mysql_fetch_object($result)) {
      // save object into array
   }
}

public function fetchRow($row){
  include("Project.php");
  $project = new Project();

  $id=$row->id;
  $project->setId($id); 

  $title=$row->title;
  $project->setTitle($title);   

  $infos=$row->info;
  $project->setInfo($infos);

  $text=$row->text;
  $project->setText($text);

  $cate=$row->category;
  $project->setCategory($cate);

  return $project;
}

If I have for example this code. How do i store the objects correctly into an array, where I grab the data from? And why can’t I make more than one object of type “Project”?

You should use the $_SESSION vars in php, To use them, add a session_start() at the beginning of your code. Then you can set vars with $_SESSION['selectaname'] = yourvar

Nothing prevent you to make a sql query like "SELECT username FROM users WHERE id = 1" and then set a $_SESSION['user'] = $queryresult

Then you’ll have this :

echo $_SESSION['user'];

"mylogin"
