Question

I was able to code this one:

<?php

      if(isset($_FILES['profile']) === true) {
          if (empty($_FILES['profile']['name']) === true) {
              echo 'Please choose a file!';
        } else {
               $allowed = array('jpg', 'jpeg', 'gif', 'png');

              $file_name = $_FILES['profile']['name']; //file   //line 75
              $file_extn = strtolower(end(explode('.' , $file_name))); //line 76
              $file_temp =  $_FILES['profile']['tmp_name']; // line 77


               if (in_array($file_extn, $allowed) === true) {
                //upload file

               } else {
                  echo 'incorrect file type. Allowed: ';
                   echo implode(' , ' , $allowed);


          }
        }

      }

      if (empty($user->data()->profile) === FALSE) {
      echo '<img src="', $user->data()->profile, '" alt= "', $user->data()->profile, '\'s Profle Image">';

      }
    ?>

and then suddenly it has an error with:

Strict standards: Only variables should be passed by reference in C:\wamp\www\coding_exam\index.php on line 76

if (empty($user->data()->profile) === FALSE) {
   echo '<img src="', $user->data()->profile, '" alt= "', $user->data()->profile, '\'s Profle Image">';

You can't use like this way $user->data()->profile. This is the problem here.
