Bug #17017: Variable superglobal variable not recognised within function and method

From: lennart.mulder@gmx.net Operating system: Linux PHP version: 4.2.0 PHP Bug Type: Variables related Bug description: Variable superglobal variable not recognised within function and method Hello :-) The definition of a variable variable as superglobal works fine when put in the main coding (i.e. not within a function or method). Example: <?php $aVariable = 'GET'; echo ${"_{$aVariable}"}; ?> The system output is: Array In the next example however, where the same code is put into a function, the resulting output is a error message instead: <?php function aFunction() { $aVariable = 'GET'; echo ${"_{$aVariable}"}; } aFunction(); ?> The system output is: Notice: Undefined variable: _GET in Bestand.php on line 6. Also when $_GET has been defined as global (which should not be necessary) this malfunction remains. Suggested intermediate solution: <?php function aFunction() { $aVariable = 'GET'; echo $GLOBALS["_{$aVariable}"]; } aFunction(); ?> -- Edit bug report at http://bugs.php.net/?id=17017&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17017&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17017&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17017&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17017&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17017&r=support Expected behavior: http://bugs.php.net/fix.php?id=17017&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17017&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17017&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17017&r=globals
