Getting these errors

Notice: Undefined variable: result in /var/www/tkclientespdo/func_selects.php on line 10

Warning: Invalid argument supplied for foreach() in /var/www/tkclientespdo/func_selects.php on line 10

Have you defined `$result` somewhere before looping it? Enable error-reporting `error_reporting(E_ALL); ini_set('display_errors', 1);` and check your logs. — Qirel, Jul 11 '17 at 18:50

Invalid argument supplied for foreach() - this $imp['nome'] might not exist ... I still waiting to see what is $result, 3er time that I asked my code is working but I use plain html instead the foreach because you never show the content of $result — Marcogomesr, Jul 11 '17 at 20:24

Update your func_selects.php as below.

<?php 
  require('functions.php');

  function call(){
    $result = impressoras();
    $imp_select = "";
    foreach( $result as $imp){
      $imp_select .= '<option value="'.$imp['nome'].'">'.$imp['nome'].'</option>';
    } 
    return $imp_select;
  }
?>
