Previous Comments: ------------------------------------------------------------------------ [2014-12-23 19:06:21] ab@php.net @jmichae3 at yahoo dot com, you can do that. Leave only one variable, remove the strtoupper() loop, remove peak usage check, etc. Please leave only what is relevant to the matter you report. Thanks. ------------------------------------------------------------------------ [2014-12-13 16:02:21] jmichae3 at yahoo dot com that *is* reduced. the source program is large and has several related files. I knew someone was going to say that, so I reduced it, but I didn't think someone was going to ask for further reduction. sorry, can't be done. the for statement's {} apparently DO have scope. once I put the global statement in {} it doesn't work. ------------------------------------------------------------------------ [2014-12-12 19:20:46] aharvey@php.net What do you mean by "doesn't work"? Can you reduce this to a minimal, runnable example, please? Note that PHP doesn't have block scope, so any loops are within the same scope as the function as a whole. ------------------------------------------------------------------------ [2014-12-12 15:20:58] jmichae3 at yahoo dot com workaround is to avoid curly braces in th efor loops altogether and nest for loops and use 2 source arrays: http://pastebin.com/RMuqU3AF ------------------------------------------------------------------------ [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.
