Req #53968 [NEW]: Non-breaking spaces are considered as a valid identifier character

From: Operating system: PHP version: Irrelevant Package: *General Issues Bug Type: Feature/Change Request Bug description:Non-breaking spaces are considered as a valid identifier character Description: ------------ Hey :-), Just a noticeable think that PHP allows is the use of non-breaking space (0x00A0) as a valid identifier character. Thus, we can have very strange code (but I love it)! See bellow. It is not a bug, just a fact that makes PHP awesome. Test script: --------------- <?php // Just for fun. class Aa Bb Cc { public function f g h ( ) { var_dump('succeed (1)'); } } $c l a s s = new Aa Bb Cc(); $c l a s s->f g h(); // Go deeper. function   ( ) { var_dump('succeed (2)'); }  (); // Go crazy! class   { public function    ( ) { var_dump('succeed (3)'); } } $  = new  (); $ ->  (); echo 'PHP is awesome :-).' . "\n"; Expected result: ---------------- string(11) "succeed (1)" string(11) "succeed (2)" string(11) "succeed (3)" PHP is awesome :-). Actual result: -------------- string(11) "succeed (1)" string(11) "succeed (2)" string(11) "succeed (3)" PHP is awesome :-). -- Edit bug report at http://bugs.php.net/bug.php?id=53968&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53968&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53968&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53968&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53968&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53968&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53968&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53968&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53968&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53968&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53968&r=support Expected behavior: http://bugs.php.net/fix.php?id=53968&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53968&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53968&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53968&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53968&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53968&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53968&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53968&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53968&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53968&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53968&r=mysqlcfg
