From: david at tulloh dot id dot au Operating system: PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: static unset documentation is unclear
Description: ------------ http://www.php.net/manual/en/function.unset.php#AEN183845 The documentation for unsetting static variables is very unclear and confusing due to it's contradictory nature. It is stated that the variable is destroyed, yet the example shows that this clearly isn't the case. Rather the variable is only temporarily destroyed, for the remainder of that function. The example provided seems to demonstrate that unset has no effect, removing the unset command produces exactly the same output. I believe changing the descriptive text and changing the example to something like the one below would make the behaviour far clearer. Reproduce code: --------------- <?php function foo() { static $bar; $bar++; echo "Before unset: $bar\n"; unset($bar); $bar = 23; echo "After unset: $bar\n"; } foo(); foo(); foo(); ?> Before unset: 1 After unset: 23 Before unset: 2 After unset: 23 Before unset: 3 After unset: 23 -- Edit bug report at http://bugs.php.net/?id=34865&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34865&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34865&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34865&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34865&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34865&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34865&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34865&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34865&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34865&r=support Expected behavior: http://bugs.php.net/fix.php?id=34865&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34865&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34865&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34865&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34865&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34865&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34865&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34865&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34865&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34865&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34865&r=mysqlcfg
