From: jeremy dot tharp at gmail dot com Operating system: Redhat Linux PHP version: 5.2.9 PHP Bug Type: Feature/Change Request Bug description: It would be nice if there were a temporary conditions control structure
Description: ------------ This isn't really a bug, but I think it would be great to have a control structure that has temporary execution parameters. Consider it an execution space similar to a while or switch, etc. The reason I could use it in this particular instance is for security reasons. For certain code, I need to elevate a logged in user's "status" to temporarily give them super user permissions. Basically I temporarily convert the user, run the code, then convert them back. convert_user(); execute_code_here(); convert_user_back(); This works great, of course, but if I have to do this 300 times, there is a decent chance that I would forget to convert_user_back();, causing a security hole (the user would then be logged in as a super user). It would be great if I could do something like execspace conversion_space ($params[]) { function start () { convert_user(); } function stop () { convert_user_back(); } } Then in my actual code, I would do: conversion_space { // start function executes here // execute some code } // stop function executes here This way, it is grammatically impossible to implement the structure without closing it. I think this would be a powerful control structure for the language. Perhaps there is an equally useful solution that I am unaware of, but if not, I think implementing it is worth consideration (and if there is, I would certainly appreciate the enlightenment!) -- Edit bug report at http://bugs.php.net/?id=47926&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47926&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47926&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47926&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47926&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47926&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47926&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47926&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47926&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47926&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47926&r=support Expected behavior: http://bugs.php.net/fix.php?id=47926&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47926&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47926&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47926&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47926&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47926&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47926&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47926&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47926&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47926&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47926&r=mysqlcfg
