This RFC proposes the removal of ASP tags ( <% ) and script tags ( <script language=php> ) as a means of entering or leaving PHP mode.

The following syntactical elements are removed:

<% opening tag

<%= opening tag with echo

%> closing tag

(<script\s+language\s*=\s*(php|"php"|'php')\s*>)i opening tag

(</script>)i closing tag

The listed opening tags will no longer enter PHP mode and the listed closing tags will no longer leave PHP mode.

Additionally the asp_tags ini directive is removed. Trying to enable asp_tags will result in a core error.
