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>';

• Mateusz Nowak: If you want to display only cities or provinces then use array_filter
• michael.schuett: 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.
• hello: @mschuett To requote the end result I wanted: "What I want to achieve is to loop those three cities at the bottom, probably with the use of the [name] => city."
• worldofjr: 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.

Answer 1

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!

• hello: Helped a lot. Need to study more about implodes and explodes. Thank you. :)

Answer 2

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?
