Req #53705 [NEW]: Add AOP & Interception Filter Support

From: Operating system: NA PHP version: Irrelevant Package: *Programming Data Structures Bug Type: Feature/Change Request Bug description:Add AOP & Interception Filter Support Description: ------------ I propose a modification to the PHP core adding the following features. (Not all inclusive, I'll try to include everything I think needs to be added). I guess this could be called interception. The official name is AOP. What it would enable you to do is intercept method calls immediately before and after they are executed. It would also enable you to filter the arguments sent to the methods. We would need: A way to enable this feature. A way to add interceptions A way to list interceptions A way to remove interceptions The ability to view interceptions in standard debug backtraces. Test script: --------------- interception::attachBefore('className', 'methodName', 'classToExecute', 'methodToExecute'); interception::attachFilter('className', 'methodName', 'classToExecute', 'methodToExecute'); interception::attachAfter('className', 'methodName', 'classToExecute', 'methodToExecute'); interception::detachBefore('className', 'methodName', 'classToExecute', 'methodToExecute'); interception::detachFilter('className', 'methodName', 'classToExecute', 'methodToExecute'); interception::detachAfter('className', 'methodName', 'classToExecute', 'methodToExecute'); $list = interception::getAll(); $list = interception::getForClass('className', [methodName]); interception::clearAll(); Expected result: ---------------- When attaching an intercept before a method call, the methodToExecute will receive the exact same arguments as the intercepted methodName. Immediately after methodToExecute has completed, methodName will then be executed. When attaching an intercept filter, the methodToExecute method will receive the exact same arguments as the intercepted methodName passed by reference (maybe). It can then modify the arguments if required. When attaching an intercept after a method call, the methodToExecute will receive the exact same arguments as the intercepted methodName in addition to the return value of methodName. -- Edit bug report at http://bugs.php.net/bug.php?id=53705&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53705&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53705&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53705&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53705&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53705&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53705&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53705&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53705&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53705&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53705&r=support Expected behavior: http://bugs.php.net/fix.php?id=53705&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53705&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53705&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53705&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53705&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53705&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53705&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53705&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53705&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53705&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53705&r=mysqlcfg
