Bug description: Ability to set new/alternative PHP parse tags
Description:
------------
Hello,
I would like to propose, as a new feature for PHP, the ability to set new
or alternative start and end tags for PHP parsing (i.e. instead of the
usual <?php and ?>).
PHP tags are useful for including PHP inside HTML documents. Doing so
makes it easier for designers to work directly inside PHP files with
minimal risk that they mess up the code.
However, a serious problem here is that PHP tags do not contrast clearly
with the surrounding HTML code, since both the current PHP tags and HTML
use brackets (< and >).
One consequence for me is that I almost always tend to avoid writing PHP
inside HTML; instead I print out long portions of HTML using PHP's echo
statement.
The solution to this dilemma would be to enable a function such as e.g.
set_php_tags($new_start_tag, $new_end_tag), which would set new start and
end tags for indicating start and end of PHP parsing.
Using such a function somewhere at the top of my script, I could then
perhaps write ##?php and ?## instead of <?php and ?> to start and end PHP
parsing inside HTML code, which would make the PHP code contrast much
clearer with the HTML code.
Security consideration:
As a security measure, I think that such optional tagging schemes perhaps
only should be valid for the particular script files in which they are
defined. (Otherwise, someone could perhaps set alternative tags in one
script file, include a script file belonging to somebody else, and then
have the whole script of that file be printed out as if it were HTML, since
its PHP parsing tags would be ignored.)

Reproduce code:
---------------
<?php
set_php_tags("##?php", "?##");
$string = "Hello World!";
?>
Here is some text:<br>
##?php echo $string; ?##<br>
End
Expected result:
----------------
Here is some text:
Hello World!
End
