if(empty($_files) === false) { for($i=1; $i<=$items; $i++) {      $allowed = array('jpg', 'jpeg', 'gif', 'png');    if (empty($_files['photo{$i}']['name']) === true) {       echo '<div class="alert alert-danger">please choose file.</div>';   } else {       if (in_array(strtolower(end(explode('.', $_files['photo{$i}']['name']))), $allowed) === false) {       echo '<div class="alert alert-danger">[photo '.$i.'] format <strong>not</strong> acceptable. ';       echo 'accepted formats: '. implode(', ', $allowed).'</div>';       } elseif($_files["photo{$i}"]['size'] > 1048576) {       echo '<div class="alert-danger">[photo '.$i.'] image big. maximium file size 1mb.</div>';       } else {         mysqli_query($con, "update temp set photo{$i} = '".rand(0,999).".".in_array(strtolower(end(explode('.', $_files['photo{$i}']['name']))))."' session = $session");         move_uploaded_file($_files["photo{$i}"]['tmp_name'], 'img/temp/'.rand(0,999) . '.' . in_array(strtolower(end(explode('.', $_files['photo{$i}']['name'])))));       }   }   } }

the image doesn't move desired uploaded location , not update file path in database. please can help?

everywhere have 'photo{$i}' incorrect. elitechief21 explained in comment above, php not parse variables in single quotes., literally looking key photo{$i} in $_files, treating {$i} literal text. of course, doesn't exist, script doesn't work expected.

you need use double quotes wherever photo{$i} inside single quotes.
