foreach loop with nested array?

Question

My array $array contains the following:

Array ( [0] => Array (
               [label] => Location and Contact
               [description] =>
      ) [1] => Array (
               [label] => Province
               [name] => province
               [options] => Array ( [0] => Province 1
                                    [1] => Province 2
                                    [2] => Province 3 )
      ) [2] => Array (
               [label] => City
               [name] => city
               [options] => Array ( [0] => City 1
                                    [1] => City 2
                                    [2] => City 3 )
      )

What I want to achieve is to loop those three cities at the bottom, probably with the use of the [name] => city.

What I've tried so far (which isn't really looking good):

foreach ($array as $arr) {

            foreach ($arr['options'] as $option) {
            ?>
            &raquo; <?php echo $option; ?><br />
             <?php
            }

}

My obvious problem with the code is the foreach loop within foreach loop plus I haven't figured out how to identify [name] => city from [name] => province, both of them having [options].

I'm fairly new to looping arrays.

UPDATE (WITH MY ANSWER)

Combining worldofjr's answer and my modification so I can enclose each loop in a container like <li>, <option>, <div>, etc, I just created two foreach's:

    foreach($array as $arr) {
        if($arr['name'] == "city") {
            $cities = $arr['options'];
        }
    }
    echo '<select>';
    foreach($cities as $city){

            echo '<option value="'.$city.'" class="class1 class2" data-att="att">'.$city.'</option>';

    }
    echo '</select>';

If you want to display only cities or provinces then use array_filter — Mateusz Nowak

You have not made it very clean what you want the end result to be. If you clarify your question you will get some better answers. — michael.schuett

To display each city in a list, you don't need the 2nd foreach. Just wrap the implode() with list tags, ie; echo "<ul><li>" . implode("</li><li>", $arr['options']) . "</li></ul>"; — worldofjr

Fair enough. It does depend on your particular situation, but if you do have a problem (and can't find an answer on SO) do ask another question. — worldofjr

You could use implode($glue,$array) as follows;

foreach($array as $arr) {
    if($arr['name'] == "city") {
        echo implode('<br>',$arr['options']);
    }
}

or if you want to print a list of the cities, wrap the implode() with list tags, like this;

foreach($array as $arr) {
    if($arr['name'] == "city") {
        echo "<ul><li>" . implode("</li><li>", $arr['options']) . "</li></ul>";
    }
}

See PHP manual: implode.

Hope this helps!

I don't understand at all, but I what you want is simply output the three cities, yo can do this

foreach ($array as $arr) 
{
    if ($arry['name'] == 'city') 
    {
        foreach ($arr['options'] as $option) 
        {
            echo $option . '<br />';
        }
    }
}

That's enough?
