PHP Nested Array - Output sub-array contents and array name

Question

Consider this nested array:

$link = array(
 'Level 1' => array(
   'Monthly' => array( 
    'note' => 'Note 1 1',
    'link'  => '1.1.com',
    ),
   '6 Month' => array(  
     'note' => 'Note 1 6',
     'link' => '1.6.com',
    ),
 ),
 'Level 2' => array(
   'Monthly' => array( 
    'note' => 'Note 2.1',
    'link'  => '2.1.com',
    ),
   '6 Month' => array(  
     'note' => 'Note 2.6',
     'link' => '2.6.com',
    ),
 ),

How would I gracefully use a foreach to achieve the following:

if $var = 'Level 1' output 

  <a href="1.1.com" title="Note 1 1">Monthly</a>
  <a href="1.6.com" title="Note 1 6">6 Month</a>

I'm suspecting I might need to do a loop inside a loop? I can iterate through the array, but am having trouble figuring out how to call the name of the sub-array...

Answer 1

<?php
$key = 'Level 1';

$link = array(
 'Level 1' => array(
   'Monthly' => array( 
    'note' => 'Note 1 1',
    'link'  => '1.1.com',
    ),
   '6 Month' => array(  
     'note' => 'Note 1 6',
     'link' => '1.6.com',
    ),
 ),
 'Level 2' => array(
   'Monthly' => array( 
    'note' => 'Note 2.1',
    'link'  => '2.1.com',
    ),
   '6 Month' => array(  
     'note' => 'Note 2.6',
     'link' => '2.6.com',
    ),
 ),
);

if(isset($link[$key])) {
    foreach($link[$key] as $array) {
        print_r($array);
    }
}
?>

RETURNS

Array
(
    [note] => Note 1 1
    [link] => 1.1.com
)
Array
(
    [note] => Note 1 6
    [link] => 1.6.com
)

I check to see if it is set first and then run a foreach on the set key to print out what you need.

EDIT:

if(isset($link[$key])) {
    foreach($link[$key] as $key => $array) {
        print $key;
        print_r($array);
    }
}

Which returns

Monthly
Array
(
    [note] => Note 1 1
    [link] => 1.1.com
)
6 Month
Array
(
    [note] => Note 1 6
    [link] => 1.6.com
)

Answer 2

I think using nested loop in this case is graceful.

Just use two foreach.

Answer 3

that's how it'd look like if you're trying to define the arrays within the main array

    foreach ($link  as $sub_array) {
        //do something
        foreach ($sub_array as $sub_of_sub) {
            // do something and so on
        }
    }
