Req #66729 [NEW]: Introduce a means to test if a function has been disabled via disable_functions

From: johnbillion+php at gmail dot com Operating system: PHP version: Irrelevant Package: *Configuration Issues Bug Type: Feature/Change Request Bug description:Introduce a means to test if a function has been disabled via disable_functions Description: ------------ Feature request. It is possible to disable PHP functions via the disable_functions directive in php.ini. However, there is no method of testing, at runtime, whether a given function has been disabled by this means, The common way to detect whether a function has been disabled is to inspect the return value of ini_get('disable_functions'). This is far from optimal, especially if ini_get() itself has been disabled. A function should be introduced which accepts a function name and returns a boolean value stating whether the function has been disabled. Example: if ( ! function_disabled('exec') ) { exec( $command ) } Alternatively, to avoid the double negative, it could be named something like function_enabled() or function_available(). -- Edit bug report at https://bugs.php.net/bug.php?id=66729&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66729&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66729&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66729&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66729&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66729&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66729&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66729&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66729&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66729&r=support Expected behavior: https://bugs.php.net/fix.php?id=66729&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66729&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66729&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66729&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66729&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66729&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66729&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66729&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66729&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66729&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66729&r=mysqlcfg
