PHP Multidimensional associative arrays

I am just wondering if this code I have is a multidimensional associative array. I only ask because after doing research on multidimensional arrays I could’t find the difference between the two because they looked the same. Is this code a associative array or just a standard multidim array?

$win = array('Name'=> 
                        array('Jane Doe ', 'Nash Patel ', 'Joe Public '), 
             'Date'=>
                        array('7 October 2015 ', '14 October 2014 ', '12 October 2016 '));

foreach($win as $element => $namedate) {
    echo '<strong>' . $element . '</strong><br>';
    foreach($namedate as $both) {
       echo $both . '<br/>';
    }
}

You have a multidimensional array.

The first level is associative because the keys are Name and Date.

The second level subarrays are indexed (not associative). This means Jane Doe’s index is 0, Nash Patel is 1, and Joe Public is 2.

Although you can if you wish, keys do not need to be written when declaring indexed elements — PHP will spare you that tedious job.

Examples:

$one_dim=['Name'=>'Jane Doe ']; // 1-dimensional associative array with one element

$one_dim=['Jane Doe '];         // 1-dimensional indexed array with one element

$mult_dim=[                     // multi-dimensional associative array with indexed subarrays
    'Name'=>[                   // associative
        0=>'Jane Doe ',         // indexed
        1=>'Nash Patel ',       // indexed
        2=>'Joe Public '        // indexed
    ],
    'Date'=>[                   // associative
        0=>'7 October 2015 ',   // indexed
        1=>'14 October 2014 ',  // indexed
        2=>'12 October 2016 '   // indexed
    ]
];
