Magento 2 Custom Email – How to Print Array Values in Custom HTML Email Template

arraycustomemail-templateshtmlmagento2.3

I want to print multiple coupon/gift codes in the custom email template. I am getting a single code as:

$templateVars = array(
    'store' => $this->storeManager->getStore(),
    'customer_name' => $name,
    'giftcods' => 'VFDFRVXSW43VF'
);

In HTML Template file:

<div style="color:#696969;font-size:20px;text-align:center;">
    <strong>{{var giftcods|raw}}</strong>
</div>

And output as:

enter image description here

But this is a single code, I won't to print multiple codes in an email.
I have gone by some related links like:

Magento 2 : How to handle array values in custom email templates?

Pass Variable And Output In Custom Email Template

But there is no proper solution available specially about how to deal with array value in the HTML template.

Edit:

In vendor/magento/module-gift-card Module this is done as

In file: vendor/magento/module-gift-card/view/frontend/email/gift_information.html

{{if is_multiple_codes}}
<h3>{{trans "Gift Card Codes:"}}</h3>
{{else}}
<h3>{{trans "Gift Card Code:"}}</h3>
{{/if}}

<p>{{var giftcards|raw}}</p>

Variables are sending by Magento\GiftCard\Model\GiftCardItemEmail.php as:

$templateData = [
    'name' => $giftCardOrderItem->getProductOptionByCode('giftcard_recipient_name'),
    'sender_name' => $senderName,
    'giftcards' => $codeList->toHtml(),
    'balance' => $balance,
    'is_multiple_codes' => 1 < $generatedCodesCount,
    'store' => $giftCardOrderItem->getStore(),
    ..................
    ..................
];

Here $codeList is not array. But still looking to solve!

Please add this to the PHP file.

$giftcods = ['VFDFRVXSW43VF', 'FFRFRFVSW43VF', 'VFDFGFGFXSW43VF'];
$templateVars = [
    'store' => $this->storeManager->getStore(),
    'customer_name' => $name,
    'giftcods' => implode("<br>",$giftcods) 
];

And set in template as ->setTemplateVars($templateVars)

Use variable in HTML as,

<div style="color:#696969;font-size:20px;text-align:center;"> 
    <strong>{{var giftcods|raw}}</strong> 
</div>

Clear cache: php bin/magento cache:clean and check it.
