My console shows no errors

Although I put "one" and "doz" as it had been done in the video, no errors were showed in the console. Did I do something wrong or it's just the console? Here's my code:

recipes.php 
<?php

class Recipe 
{
  private $title;
  public $ingredients = array();
  public $instructions = array();
  public $yield;
  public $tag = array();
  public $source = "ลฝeljko Porobija";

  private $measurements = array(
   "tsp",
    "tbsp",
    "cup",
    "oz",
    "lb",
    "fl oz",
    "pint",
    "quart",
    "gallon"
  );

  public function setTitle($title) 
  {
    $this->title = ucwords($title);
  }

  public function getTitle()
  {
   return $this->title;    
  }

  public function addIngredient ($item, $amount = null, $measure = null)
  {
    if ($amount != null && is_float($amount) && !is_int($amount)) {
     exit("The amount must be a float: " .gettype($amount). " $amount given"); 
    }
    if ($measure != null && in_array(strtolower($measure), $this->measurements)) {
     exit("Please, enter a valid measurement: " .implode(", ", $this->measurements)); 
    }
     $this->ingredients[] = array(
      "item" => ucwords($item),
      "amount" => $amount,
      "measure" => strtolower($measure)    
    );
  }


  public function displayRecipe()
  {
    return $this->title . " by " .$this->source;
  }
}

$recipe1 = new Recipe();
$recipe1->source = "Grandma Holligan";
$recipe1->setTitle ("my first recipe");
$recipe1->addIngredient("egg", "one", "doz");

$recipe2 = new Recipe();
$recipe2->source = "Bettie Crocker";
$recipe2->setTitle("My Second Recipe");

echo $recipe1->getTitle();
echo $recipe1->displayRecipe();
echo $recipe2->displayRecipe();

I'm not entirely sure what you're trying to do and haven't seen the video, but at a glance your conditions are wrong. if you want a float, you probably want your error condition to be ($amount == null || !is_float($amount)). The measure condition also needs to be inverted, i think. ($measure == null || !in_array(strtolower($measure), $this->measurements))

if you want a little more variety in terms of what your type can be, you might want to us is_numeric. (this confirms that a value is a float, int or valid numeric string)

Yep, I missed an ! before is_float, it seems that it was the problem.
