The alternative PHP tags <% (and <%=), %>, <script language=”php”>, and </script> have been removed in PHP7.
Additionally the asp_tags ini directive is removed. Trying to enable asp_tags will result in a core error.
If your code relied upon these alternative tags, then they need to be updated to either the normal or short opening and closing tags.
Still we have support for short opening tags (<?) or short opening tags with echo (<?=).
That is it.
