#39541 [NEW]: next_key() and prev_key()

From: boots@php.net Operating system: all PHP version: 5.2.0 PHP Bug Type: Feature/Change Request Bug description: next_key() and prev_key() Description: ------------ It would be handy if PHP had functions to get the current and previous keys in an array without affecting the current array pointer. Presently, one must use prev()/key() next()/key() and these both affect the array pointer. This is inconvenient when looping through an array with the intention of comparing the current item to its immediate neighbors. Having next_key() and prev_key() would allow one to directly lookup the neighboring items without affecting the current position while looping. -- Edit bug report at http://bugs.php.net/?id=39541&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39541&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39541&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39541&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39541&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39541&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39541&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39541&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39541&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39541&r=support Expected behavior: http://bugs.php.net/fix.php?id=39541&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39541&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39541&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39541&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39541&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39541&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39541&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39541&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39541&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39541&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39541&r=mysqlcfg
