如何在phpfox中打印数组的内容

I'm working on a legacy application that is written in PHPfox.

There is this foreach loop in one of my view.html.php files:

{foreach from=$aReportSubmissions key=iKey item=aReportSubmission}
    <td>{$aReportSubmission.event_name}</td>
{/foreach}

The problem is that $aReportSubmission.event_name is an array and it gets outputted as Array. How can I loop through this variable and show the individual events?

PHPfox uses template tags that resemble Smarty template engine.

The following did NOT work for me:

{foreach from=$aReportSubmission.event_name item=iEvent} {iEvent},{/foreach}

I can see $ is missing before iEvent inside the inner loop

Check if this is works

{foreach from=$aReportSubmissions key=iKey item=aReportSubmission}
    <td>{foreach from=$aReportSubmission.event_name item=iEvent} {$iEvent},{/foreach}</td>
{/foreach}

Try with this

 {foreach from=$aReportSubmissions key=iKey item=aReportSubmission}
    {$aReportSubmission.event_name|print_r}
{/foreach}
