Looping with PHP

I have done it with my Code Editor and everything is working properly but here is somehow not working.

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);


$status = 'available';

foreach ($flavors as $flavor){
    if($status === 'available' || $flavor['in_stock'] == $status)
      echo "<li>";
      echo $flavor['name'];
      echo "</li>";
}

?>

I don't think you should use $status === 'available' as the previous poster mentioned. Since that will always be true.

I did it using a foreach loop, then checking the selected items 'in_stock' value as true or false. If true, then display the name of the flavor. 

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

In the line if($status === 'available' || $flavor['in_stock'] == $status), $status === 'available' is always true since the value of $status is not changed. You could change || to && so that both conditions must be true, or change the line to if($flavor['in_stock'] == true) or if($flavor['in_stock']).

Instead of 

      echo "<li>";
      echo $flavor['name'];
      echo "</li>";

try echo $flavor;. The challenge is not expecting the flavors to be list items.

To do multiple statements after an if statement, you could try surrounding the code block with { and }, such as 

    if($flavor['in_stock']) {
      echo "<li>";
      echo $flavor;
      echo "</li>";
    }

but this does not pass the challenge. If you leave off the { and }, only the first line after the if statement is inside the if block, and the lines after the first line will run regardless of the truthiness of the if statement's condition.
