I need help fixing my php syntax to make my code work.

class Post {

private $user_obj; private $con;

public function __construct($con, $user) { $this ->con = $con; $this->user_obj = new User($con, $user); }

public function loadPostsFriends() {

$str = ""; // String to return $data = mysqli_query($this->con, "SELECT * FROM posts WHERE deleted='no' ORDER BY id DESC"); while($row = mysqli_fetch_array($data)) {

$id = $row['id']; $body = $row['body']; $added_by = $row['added_by']; $date_time = $row['date_added'];

// Prepare user_to string so it can be included even if not posted to a user

if($row['user_to'] == "none") { $user_to = ""; }

else { $user_to_obj = new User($con, $row['user_to']); $user_to_name = $user_to_obj->getFirstAndLastName(); $user_to = "". $user_to_name. ""; }

// Check if user who posted has their account closed

$added_by_obj = new User($con, $added_by); if($added_by_obj->isClosed()) { continue; }

$user_details_query = mysqli_query($this->con, "SELECT first_name, last_name, profile_pic FROM users WHERE username='$added_by'"); $user_row = mysqli_fetch_array($user_details_query);

}

// timeframe $date_time_now = date("Y-m-d H:i:s"); $start_date = new DateTime($dat_time); // Time of post $end_date = new DateTime($date_time_now); // Current time $interval = $start_date->diff($end_date); // Difference between dates if ($interval ->y>= 1) { if($interval == 1) $time_message = $interval->y . "year ago "; // 1 year ago else $time_message = $interval->y . "years ago "; // years ago }

else if ($interval-> m >= 1) { if($interval->d == 0) { $days = " ago"; } else if ($interval-> d >= 1) $days = $interval->d . "day ago"; } else { $days = $interval->d. "days ago";

}

if($interval->m ==1) { $time_message = $interval->m . "month".$days; } else {

$time_message = $interval->m . "months".$days;

}

else if($interval->d >=1) { if ($interval->d == 1) { $days = "Yesterday"; } else { $time_message = $interval->d . "days ago"; } }

public function submitPost($body, $user_to) { $body = strip_tags($body); // removes any html tags $body = mysqli_real_escape_string($this->con, $body); $check_empty = preg_replace('/\s+/', '', $body); // Deletes all spaces

if($check_empty != "") {

// Current date and time $date_added = date("Y-m-d H:i:s");

// Get username

$added_by = $this->user_obj->getUsername();

// If user is on own profile, user_to is 'none'

$user_to = "none"; }

// inset post into database
