PHP PHP Arrays and Control Structures PHP Loops Looping with PHP

for task 3 of 3 for foreach loop PHP code challenge- am I going about this correctly?

Am I going about this correctly? I feel like I'm either very close or way off base.

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 $value){
  if ($value['in_stock'] = true) {
  echo $value['name'];
  }
?>

Hey Matthew Lawson,

you're very close! You forgot the extra = sign in your if. So your code should change from this:

if ($value['in_stock'] = true)

to this:

if ($value['in_stock'] == true) {

But you could also do (as an alternative):

if ($value['in_stock']) {

for cleaner code.

The reason why it was still working for you is because you were doing an assignment - you were setting $value['in_stock'] to true. The assignment it self is successful (aka true) so the if gets executed.
