XF Page + php


Well-known member
I want to put a feed into an XF Page from a site where I hold a bibliography of listings.
But I don't understand how to enter their php snippet under the PHP tab on the XF Page.

The PHP snippet I should enter is:

<?php $URL= ‘https://api.zotero.org/groups/mabinogistudy/items?format=bib&style=apa’?>
<?php $var= file_get_contents($URL)?>
<?php echo $var ?>
The URL for my bibliography source is

However I was unable to Copy the php snippet from the instruction as it was an image file.
Here it is. phpzotero.png
