From: david dot proweb at gmail dot com Operating system: PHP version: Next Major Version Package: PHP Language Specification Bug Type: Feature/Change Request Bug description:Support to swap() function Description: ------------ This function should swap two variables. Currently it can be done by code a swap function, like: function swap(&$a, &$b) { $tmp = $a; $a = $b; $b = $tmp; } I think that should be useful PHP do it alone, and simple to include it on code. -- Edit bug report at https://bugs.php.net/bug.php?id=70736&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70736&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70736&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70736&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70736&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70736&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70736&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70736&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70736&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70736&r=support Expected behavior: https://bugs.php.net/fix.php?id=70736&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70736&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70736&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70736&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70736&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70736&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70736&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70736&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70736&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70736&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70736&r=mysqlcfg
