Modify the foreach loop to display only the flavors that are in stock

I got it to display the correct flavors and was excited but then it said that it wasn't correct and task 2 was no longer passed???

index.php 
<?php

$flavors = array();
$flavors[] = array("name" => "Cookie Dough",      "in_stock" => true);
$flavors[] = array("name" => "Vanilla",           "in_stock" => false);
$flavors[] = array("name" => "Avocado Chocolate", "in_stock" => false);
$flavors[] = array("name" => "Bacon Me Crazy",    "in_stock" => true);
$flavors[] = array("name" => "Strawberry",        "in_stock" => false);

//add your code below this line
foreach ($flavors as $flavor) if($flavor["in_stock"]==true) {echo $flavor["name"] . "<br />\n"; } ?>

try to do it with the brackets around the foreach and also remove the "==true" from the if statement

If you format this you'll see that you're just missing brackets

foreach(){
  if(){

  }
}

I ran your code, and it perfectly works fine for me, try running your code yourself.

I agree with both Haris and Dave, make it a habit of indenting the code, it will be best practice to have the code like as

<?php
foreach ($flavors as $flavor){
  if ($flavor["in_stock"]){
  echo $flavor["name"]."<br>";
  }
}
?>

I went with the simplest solution 

<?php

$flavors = array();
$flavors[] = array("name" => "Cookie Dough",      "in_stock" => true);
$flavors[] = array("name" => "Vanilla",           "in_stock" => false);
$flavors[] = array("name" => "Avocado Chocolate", "in_stock" => false);
$flavors[] = array("name" => "Bacon Me Crazy",    "in_stock" => true);
$flavors[] = array("name" => "Strawberry",        "in_stock" => false);

//add your code below this line
foreach ($flavors as $flavor){
    //var_dump($flavor);
    if ($flavor['in_stock'] == true){
    echo $flavor['name'];
  }
}
?>
