Edit report at https://bugs.php.net/bug.php?id=68595&edit=1 ID: 68595 Comment by: jmichae3 at yahoo dot com Reported by: jmichae3 at yahoo dot com Summary: variable variables scope problem in for loops Status: Open Type: Bug Package: Scripting Engine problem Operating System: windows 7 sp1 x64 PHP Version: 5.5.19 Block user comment: N Private report: N New Comment: workaround is to avoid curly braces in th efor loops altogether and nest for loops and use 2 source arrays: http://pastebin.com/RMuqU3AF Previous Comments: ------------------------------------------------------------------------ [2014-12-12 15:03:58] jmichae3 at yahoo dot com Description: ------------ global keyword doesn't work in for loops because of scope issues I guess. causes a problem with my code, which wants to generate a collection of variable variables. I must manual,ly declare them all rather than iterating through the loop. the variable variables generated for stats are: $VISITORfilecount $VISITORfoldercount $VISITORhttpcount $ADMINfilecount $ADMINfoldercount $ADMINhttpcount $PAIDWEBAPPSfilecount $PAIDWEBAPPSfoldercount $PAIDWEBAPPShttpcount ... you COULD generate them using a nested for loop, which might be next. theoretically. but it doesn't work practically. because of scope problems, code fails in the Report() function and variable is invisible unless you have the line global ${'VISITORfilecount'}; in the code (as in the example), normally this would not be in my code, because the list of VISITOR... changes with the web sites I configure for in the config file in which this resides - manually globalling is unnecessary.
