Req #55440 [NEW]: Internal state of the execution engine

From: Operating system: PHP version: 5.3.6 Package: *General Issues Bug Type: Feature/Change Request Bug description:Internal state of the execution engine Description: ------------ While developing in PHP, I've learned that the execution engine is sometimes set in special states that alter its capabilities. As far as I know, their is no way for us developers to write code that test for one of these particular state and branch code appropriately. By "special state", I mean : - execute/compile stage, where for eg autoloading doesn't work (http://bugs.php.net/42098), - outside/inside output buffering handler, where for eg print_r($v, true) doesn't work (http://bugs.php.net/55428), - before/after "shutdown time", where for eg uncatched exceptions generate the cryptic "Fatal error: Exception thrown without a stack frame in Unknown on line 0" and set_exception_handler() is disabled. Adding a centralized way to check for these states is maybe a good idea ? For example, get_engine_state( void ) would return a bit field, each bit for each possible state? -- Edit bug report at https://bugs.php.net/bug.php?id=55440&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55440&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55440&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55440&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55440&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55440&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55440&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55440&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55440&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55440&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55440&r=support Expected behavior: https://bugs.php.net/fix.php?id=55440&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55440&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55440&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55440&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55440&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55440&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55440&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55440&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55440&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55440&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55440&r=mysqlcfg
