Re: Why is this array_walk_recursive action not working?

Hi, Well, first array_walk_recursive returns a boolean so what you are doing in you script is append a boolean (true or false) that will be converted to string. So if array_walk_recursive will return true you will have the string "1" in $karamohOutput['test'], and if array_walk_recursive will return false you will have the empty string "" in $karamohOutput['test']. I think what you're after is this: $karamohOutput['test'] = ""; foreach ( new RecursiveIteratorIterator( new RecursiveArrayIterator( $karamohArray ) ) as $key => $item ) { $karamohOutput['test'] .= "$key holds $item\n"; } On Thu, Feb 24, 2011 at 5:15 PM, Dave M G <martin@autotelic.com> wrote: > FeIn, > > Thank you for responding. > > > > what did you expect to happen when you call array_walk_recursive? > > > What I don't understand is why it did not append to the string as it > walked through each key/value pair. > > It seems like even though the variable inside the function called by > array_walk_recursive has the same name as a global variable, it gets > treated as if it only has local scope and nothing done to it applies to > the global variable. > > -- > Dave M G > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > >
