I am working on content-based filtering algorithm using PHP. I'm trying to retrieve user data from the table using the query "$user = [$db, "SELECT interest FROM jobseeker WHERE username = '$username'"];" it shows the warning as in comment:

protected function processUser($user)
{
    $result = [];
    foreach ($user as $tag) {
        $result[$tag] = 1.0; //illegal offset type on this line
    }
    return $result;
}

Also while fetching objects from the table using the query

$objects = [$db, "SELECT job_title, category FROM job_data"];

it shows another warning as in comment:

  protected function processObjects($objects)
    {
        $result = [];
        foreach ($objects as $object => $tags) {
            foreach ($tags as $tag) //invalid argument supplied for foreach() 
                         {

What would be the valid argument for this case?? I've tried this query as for this case:

$objects = [($db,"SELECT job_title from jobs") => [$db, "SELECT name FROM categories"]];

Still it didn't work as it gave error unexpected on this query

Well, what's inside `$user` and `$object`? – m02ph3u5 Jul 27 '19 at 21:36
The $user contains user's preference an $object contains job titles that are similar to user's preference – Aayush Niraula Jul 27 '19 at 22:49
