No objection to discourage use of <?, <?=,<% and <%= if there is
open tag with echo.

<?php= is less ambigiuos than <?= or <%=. Lack of <?php= is
encouraging use of <%= or <?=. IMHO.
Some people, including me, prefer to use open tag with echo
since it looks better on source *mostly* written in HTML.
We use template feature came with WISWYG HTML editor. Almost all
php values and ouputs are printed by open tag with echo. Getting
rid of template handling burden from PHP improves performance and
makes collaboration with HTML designer easier, since templates
and pages generated are almost complete HTML. It's possible
without open tag with echo, though.
I'm not sure how others feels, but it looks better and easier to
read for me if there is open tag with echo... With "<?php echo" or
"<?php print", it seems I need extra step in my brain to read.:)
Following HTML/PHP source is very simpile, but you might be
able to see the difference. For complex HTML/CSS with PHP, the
difference is obvious to me, at least.
<html>
<head>
<title><?php= CurrentTitle() ?></title>
</head>
<body>
<table>
<tr>
<td colspan="2"><?php= LoginStatus() ?></td>
</tr>
<tr>
<td colspan="2"><?php= $Message ?></td>
</tr>
<tr>
<td>Login Name</td>
<td><?php= $LoginName ?></td>
</tr>
<tr>
<td>First Name</td>
<td><?php= $FirstName ?></td>
</tr>
<tr>
<td>Last Name</td>
<td><?php= $LastName ?></td>
</tr>
<tr>
<td>Login Options</td>
<td><?php= $LoginOptions ?></td>
</tr>
</table>
</body>
</html>
With "<?php echo", it seems I need extra step in my brain to read.
It may be related that I read/write Kanji. I guess it depends on
how you search patterns in text in your brain...
<html>
<head>
<title><?php echo CurrentTitle() ?></title>
</head>
<body>
<table>
<tr>
<td colspan="2"><?php echo LoginStatus() ?></td>
</tr>
<tr>
<td colspan="2"><?php echo $Message ?></td>
</tr>
<tr>
<td>Login Name</td>
<td><?php echo $LoginName ?></td>
</tr>
<tr>
<td>First Name</td>
<td><?php echo $FirstName ?></td>
</tr>
<tr>
<td>Last Name</td>
<td><?php echo $LastName ?></td>
</tr>
<tr>
<td>Login Options</td>
<td><?php echo $LoginOptions ?></td>
</tr>
</table>
</body>
</html>
Since there is no <?php=, I use <%= as follows currently.
It works fine, but it's not portable. <% is not enabled by
default. Lack of <?php= is encouraging use of <%= at least
for me.
<html>
<head>
<title><%= CurrentTitle() %></title>
</head>
<body>
<table>
<tr>
<td colspan="2"><%= LoginStatus() %></td>
</tr>
<tr>
<td colspan="2"><%= $Message %></td>
</tr>
<tr>
<td>Login Name</td>
<td><%= $LoginName %></td>
</tr>
<tr>
<td>First Name</td>
<td><%= $FirstName %></td>
</tr>
<tr>
<td>Last Name</td>
<td><%= $LastName %></td>
</tr>
<tr>
<td>Login Options</td>
<td><%= $LoginOptions %></td>
</tr>
</table>
</body>
</html>
