Req #77532 [NEW]: foreach just over keys

From: jerry at jmweb dot net Operating system: n/a PHP version: Irrelevant Package: PHP Language Specification Bug Type: Feature/Change Request Bug description:foreach just over keys Description: ------------ Too often I do something like: foreach( $array as $key => $noop ) { // do something with $key only } Why not use array_keys? Well, I guess to avoid the overhead of calling a function. It would be super if we could simply do: foreach( $array as $key => null ) { // do something with $key only } I am not 100% set on using null, but I will let the community decide on the specifics. -- Edit bug report at https://bugs.php.net/bug.php?id=77532&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77532&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77532&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77532&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77532&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77532&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77532&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77532&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77532&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77532&r=support Expected behavior: https://bugs.php.net/fix.php?id=77532&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77532&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77532&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77532&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77532&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77532&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77532&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77532&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77532&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77532&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77532&r=mysqlcfg
