#39557 [NEW]: Make functions accept superglobals as default value for its args

From: hermanscheele at gmail dot com Operating system: * PHP version: 5.2.0 PHP Bug Type: Feature/Change Request Bug description: Make functions accept superglobals as default value for its args Description: ------------ This is really a request to make an exception to the following limitation: "The default value must be a constant expression, not (for example) a variable, a class member or a function call." Quoted from: http://nl2.php.net/manual/en/functions.arguments.php It's my guess that this has to do with the vars scope getting messy, but I think superglobals would qualify for an exception to this. Constants are already accepted. Reproduce code: --------------- function foo($bar=$_SERVER['REMOTE_ADDR']) { echo('Given IP is: '.$bar.'<br />'); } foo('192.168.1.1'); foo(); Expected result: ---------------- I would expect PHP to echo the submitted string the first function-call. And echo the clients IP the second call. Actual result: -------------- I get the following parse error, which is correct, but not desirable I think. Parse error: parse error, unexpected T_VARIABLE in path\to\file.php on line 1 -- Edit bug report at http://bugs.php.net/?id=39557&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39557&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39557&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39557&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39557&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39557&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39557&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39557&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39557&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39557&r=support Expected behavior: http://bugs.php.net/fix.php?id=39557&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39557&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39557&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39557&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39557&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39557&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39557&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39557&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39557&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39557&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39557&r=mysqlcfg
