Description: ------------ I think that PHP would benefit greatly by implementing a feature known as "resumeable" exceptions. The end goal would be to provide a method by which code execution may be continued from the point at which an exception was thrown. Naturally, some exceptions should not be resumeable by nature, which would require an extension to the Exception class of a simple boolean property indicating whether an instance of that exception can be resumed or not. The only real problem AFAICS with resumeable exceptions has to do with the state of the execution stack. Obviously, if execution were to be resumed after an exception is handled, the stack can not be unwound automatically (Schrodinger's cat, anyone?). My suggestion would be to allow another keyword besides "catch" (such as "resume") to handle exceptions. If a resumeable exception is thrown and caught in a "resume" block, the parser should proceed as if it were handling a function call. In short, the unwinding of the execution stack would need to be deferred until it is determined whether or not execution will be resumed at the point of the exception. -- Edit bug report at http://bugs.php.net/?id=50726&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50726&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50726&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50726&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50726&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50726&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50726&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50726&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50726&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50726&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50726&r=support Expected behavior: http://bugs.php.net/fix.php?id=50726&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50726&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50726&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50726&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50726&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50726&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50726&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50726&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50726&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50726&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50726&r=mysqlcfg
