Req #68530 [NEW]: Which parameters to send to a function

From: ignasimg at gmail dot com Operating system: Irrelevant PHP version: Irrelevant Package: *General Issues Bug Type: Feature/Change Request Bug description:Which parameters to send to a function Description: ------------ Recently I did a wrapper for JSON_encode and JSON_decode, to deal with non UTF8 strings aswell, I tested them and didn't had any issue. The problem came when I uploaded the code to my production server, which doesn't have the same php version as my development computer. both JSON_encode and JSON_decode have signatures that added new parameters quite recently, so my server was expecting those calls with 1/2 parameters and when it seen 3 it went WTF? I needed that code asap so instead of upgrading my server to the most recent version I just deleted the noisy parameters from the code (I was not really using them, just to make the wrappers more convinient in the future) But then it came to my mind, it could be of great use a function which given reference to a function can tell (at least) how many parameters it expects. Or even better, named parameters. Would solve funny issues like: JSON_encode defines options parameter in 5.3.0 and depth in 5.5.0 and JSON_decode defines options parameter in 5.4.0 and depth in 5.3.0 Anyway just an idea : ) -- Edit bug report at https://bugs.php.net/bug.php?id=68530&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68530&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68530&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68530&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68530&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68530&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68530&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68530&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68530&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68530&r=support Expected behavior: https://bugs.php.net/fix.php?id=68530&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68530&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68530&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68530&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68530&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68530&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68530&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68530&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68530&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68530&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68530&r=mysqlcfg
