What were you expecting it would show? print_r would only show the properties in an object in this case. which the class doesn't, have a field. try adding a property and you would see the value print with print_r. like this:

PHP Code:

<?php
class FeildHTML
{
  public $state = 'not set'; //I added this property

  public function setFeildCheck ($field,$fieldval,$unsetbutton)
  {
    $field = array($field);
    $fieldval = array($fieldval);
    $label = array_combine($field,$fieldval);
    unset($_POST [$unsetbutton]);
    foreach($_POST as $k=>$v)
    {
      $$key = $v;
      echo $label[$k]."=$v<br />";
    }

    $this->state = 'set';
  }
}

$a = new FeildHTML();
$a->setFeildCheck('a','b','c');
print_r($a);
?>
//print_r output is this:
FeildHTML Object
(
    [state] => set
)
