From: ntpt at seznam dot cz Operating system: linux PHP version: 5.2.12 PHP Bug Type: *Programming Data Structures Bug description: return() in short-circuit / lazy evaluation Description: ------------ please allow return() in lazy evaluation /short-circuit syntax like $result=do_something($blah) or die('nothing done'); // this works but $result=do_something($blah) or return(false) ; // does NOT work I thing it is prety legitimate not only to call die() if do_something() return false, but in this case return() from function or include() as well. I thing it is more cleaner and readable then bunch of $result=do_something($blah) if ($result==false){ return false;} // use you result here Maybe even codeblock after "or" is worth of considerations $result=do_something($blah) or { // codeblock, do what you want here } -- Edit bug report at http://bugs.php.net/?id=50515&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50515&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50515&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50515&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50515&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50515&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50515&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50515&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50515&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50515&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50515&r=support Expected behavior: http://bugs.php.net/fix.php?id=50515&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50515&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50515&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50515&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50515&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50515&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50515&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50515&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50515&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50515&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50515&r=mysqlcfg
