I want a foreach loop to print out the three countries in the country array - (England, Wales, Scotland).

I have tried loops such as;

@foreach ($locations['country'] as $country)
 {{ $country }}
@endforeach

I have tried other variations of this but to no avail. What is the correct syntax? Also, can someone explain how I can interpret this so I can better understand foreach with arrays in future? I normally just end up guessing until I get the right result - but for a change I'd like to actually know how to put one together if that makes sense..

I am using Laravel if it helps...

Solution

What you're looping over isn't an array. It's a Laravel Collection. However it behaves like an array so it doesn't really matter. The loop itself actually looks correct. But instead of just outputting $country you have to actually access the attribute on $country called country:

@foreach($locations['country'] as $location)
    {{ $location->country }}
@endforeach

---

In general a foreach loop goes over every item in an array or collection and put's that item into the variable you define after as. Maybe this explanation helps too.

---

As a little extra: Laravel has a nice lists() function which builds an array out of an attribute from every model in a collection.

$countries = $locations['country']->lists('country');

Would result in something like:

['England', 'Wales', 'Scotland']

And you could then use functions like implode() to generate a comma separated list:

implode(', ', $countries); // returns 'England, Wales, Scotland'
