Render multimensional array in Twig

I have array like this in my controller :

foreach ($entities as $temp) {
    $semesters[]['romanic'] = $data1;
    $semesters[]['grouping'] = data2;
}

I can render it if my array like this $semesters['romanic'][]. But for some reason I can't make it like that. I've try several times like this :

{% for semester in semesters %}
{{ semester['romanic'] }} 
{{ semester['grouping'] }}
{% endfor %}

or 

{% for key, semester in semesters %}
{{ semesters[key]['romanic'] }} 
{{ semesters[key]['grouping'] }}
{% endfor %}

I can render this if using 2 loops :

{% for semester in semesters %}
{% for temp in semester %}
{{ temp }} 
{% endfor %}
{% endfor %}

But I need to do this with just 1 loop. Is this possible to do?

The first thing you should probably change is creating your array in PHP to:

foreach ($entities as $temp) {
    $c = count($semesters);
    $semesters[$c]['romanic'] = $data1;
    $semesters[$c]['grouping'] = $data2;
}

And in your Twig you can simple use:

{% for item in semesters %}
  {{ item.romanic }} {{ item.grouping }}<br />
{% endfor %}

Here's the sample PHP code to test it:

$semesters = array();

$semesters[0]['romanic'] = 1;
$semesters[0]['grouping'] = 2;
$semesters[1]['romanic'] = 3;
$semesters[1]['grouping'] = 4;
$twig->addGlobal ('semesters', $semesters);
echo $twig->render('index.html.twig');

The result is:

1 2 
3 4

as expected
