Req #63423 [NEW]: short open tag should be distinguished from other processing instructions

From: code at henrik-gebauer dot de Operating system: all PHP version: Irrelevant Package: *Compile Issues Bug Type: Feature/Change Request Bug description:short open tag should be distinguished from other processing instructions Description: ------------ The short open tag is very useful for readable templates: <?=$var?>, <? foreach ($array as $v): ?>, <? foreachend; ?> etc. But on the other hand it interferes with other processing instructions like <?xml version="1.0" encoding="utf-8"?> or <?xml-stylesheet href="style.css" type="text/css" media="all" ?> So you have to use <?="<?"?>xml version="1.0" encoding="utf-8"?> or something similar in your template which makes it less readable. The compiler should distinguish between a short PHP tag and other processing instructions. If the compiler is not sure if "<? something" is PHP code or not it should report an error as before. Test script: --------------- <?xml version="1.0" encoding="utf-8"?> <?="hello world\n";?> <?php echo "hello world\n"; ?> Expected result: ---------------- <?xml version="1.0" encoding="utf-8"?> hello world hello world Actual result: -------------- Parse error: syntax error, unexpected 'version' (T_STRING) in ... on line 1 -- Edit bug report at https://bugs.php.net/bug.php?id=63423&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63423&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63423&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63423&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63423&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63423&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63423&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63423&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63423&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63423&r=support Expected behavior: https://bugs.php.net/fix.php?id=63423&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63423&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63423&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63423&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63423&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63423&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63423&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63423&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63423&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63423&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63423&r=mysqlcfg
