3,479 PointsAccessing an array inside an array with a foreach loop
When I input my code I'm creating the correct output for the question, but I'm being told I'm not using the variable in my foreach loop. Where am I going wrong?
<?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 $key => $item) {
foreach($item as $key => $name){
if($key == 'name'){
echo $name . "\n";
}
}
}
?>
