From: mwood at IUPUI dot Edu Operating system: any PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: Needs explicit statement on falling off the end of a function Description: ------------ There is no official statement of the meaning of exiting a function other than through a 'return' statement. Specifically, it is possible to execute to the end of the function, but then what is the value of that invocation? Reproduce code: --------------- --- From manual page: language.functions --- Not in "returning values" or "return()" either. "Returning values" is probably the best place for it. Expected result: ---------------- Since many other languages will use the value of the last expression evaluated as the return value of a function which does not explicitly 'return', it would be helpful to note prominently that PHP (apparently) does not do this. It seems that the value of an invocation of such a function is NULL. -- Edit bug report at http://bugs.php.net/?id=50208&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50208&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50208&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50208&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50208&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50208&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50208&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50208&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50208&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50208&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50208&r=support Expected behavior: http://bugs.php.net/fix.php?id=50208&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50208&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50208&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50208&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50208&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50208&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50208&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50208&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50208&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50208&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50208&r=mysqlcfg
