Req #61455 [NEW]: Warn when ini_set()'ing certain directives

From: Operating system: N/A PHP version: 5.3.10 Package: PHP options/info functions Bug Type: Feature/Change Request Bug description:Warn when ini_set()'ing certain directives Description: ------------ If ini_set() is called to set any PHP directive whose 'Changeable' attribute (e.g. as per man page http://php.net/ini.list) is not 'PHP_INI_USER' or 'PHP_INI_ALL', an error message could be generated to advise the developer that the statement will have no effect. In other words, don't quietly allow directives to be changed when they've already taken effect by the time the script is executed (thus changing them via ini_set() won't ever do anything). Test script: --------------- <?php ini_set('allow_url_fopen', '1'); Expected result: ---------------- Warning: Changing PHP directive at runtime has no effect in <code> on line 3 -- Edit bug report at https://bugs.php.net/bug.php?id=61455&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61455&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61455&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61455&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61455&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61455&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61455&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61455&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61455&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61455&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61455&r=support Expected behavior: https://bugs.php.net/fix.php?id=61455&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61455&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61455&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61455&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61455&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61455&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61455&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61455&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61455&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61455&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61455&r=mysqlcfg
