PHP: rfc:remove_alternative_php_tags
Date: 2014-09-09
Status: Accepted
Targeting: PHP 7
Proposal
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*>)iopening tag(</script>)iclosing 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.
This RFC does not remove short opening tags (<?) or short opening tags with echo (<?=).
Reasoning
The alternative PHP tags have never gained any significant degree of usage. Their usage has been discouraged since forever.
The ASP tags depend on an ini directive and as such are non-portable. We generally try to move away from ini-dependent language behavior. With ASP tags removed, short open tags should be the last.
Supporting different tags allows very weird mixing like
<script language=php> echo "foo" %>
To simplify porting of legacy code using the alternative tags, a porting script is provided. The script takes a directory and will replace ASP and script tags in all .php files contained in this directory:
php -d asp_tags=1 portAlternativeTags.php dir/
