Req #76036 [NEW]: Preporocessor directrives

From: obadja dot hauser at gmail dot com Operating system: ALL PHP version: Irrelevant Package: *Programming Data Structures Bug Type: Feature/Change Request Bug description:Preporocessor directrives Description: ------------ In some cases can i need this feature. I think, this was a possible way to made code to running with modern features PHP >= 7 and on old Versions. Or to write fine granular code. Or transparence and clearer code. The preprocessor directives should recognized following: - #<preprocessor type> <preprocessor identifier> < - <preprocessor type>: #IF, #IFNOT followed by #ENDIF. Between ca #ELSE or/and #ELSEIF - <preprocessor identifier>: PHPVAR (PHP Version), OSVAR (OS Version), OS (OS Name), HTTPSRV (Webserver Name) and CLI (if true if running via cli command). It should possible to concatenate with AND. - <comparer>: <,<=,>,>=,= (= if the default comparer an is not needed to write it) - <compare value>: will always interpreted as string or number for the compare var Is there this feature planned or on your todo list :) Test script: --------------- My idea was so, e.g. class function: #IF PHPVER >= 8.0 public function getAndCatchMethod(string $methodname) : callable on throws \MyException #ELSE public function getAndCatchMethod(string $methodname) : callable #ENDIF { return [$this, $methodname]; } Expected result: ---------------- Code dynamical builded on preprocessor directives. #IF PHPVER >= 8.0 public function getMagic(string $value = '') : callable on throws \MyException { # this new killer feature will catching the Exception automatically to given Exception Class without to need try..catch, if method called ;) return [$this, $methodname]; } Class->getAndCatchMethod('test') MyException::catch() {} #ELSE public function getAndCatchMethod(string $methodname) : callable { # regular exception catching return [$this, $methodname]; } try { Class->getAndCatchMethod('test') } catch (...) { } Actual result: -------------- Nothing. This will not working at this time. -- Edit bug report at https://bugs.php.net/bug.php?id=76036&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76036&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76036&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76036&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76036&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76036&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76036&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76036&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76036&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76036&r=support Expected behavior: https://bugs.php.net/fix.php?id=76036&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76036&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76036&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76036&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76036&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76036&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76036&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76036&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76036&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76036&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76036&r=mysqlcfg
