Hi!

Hi: like the following script: <?php $str = (string)array(); echo $str;
    it is obviously intentionally convert a array to string ,  but the
warning is coming:

I think it's the correct way to react for PHP. This code is an extremely convoluted way to write "echo 'Array';" and as such doesn't seem to do anything useful. I have yet to see one single instance where converting array to string made any sense. Of course, As for the warning in 60174, it seems to be a bug indeed - the code there has no business converting any arrays to strings and in general the engine shouldn't apply make_printable_zval to arrays knowingly - there's no useful result that can come from that as far as I can see. So if you know more of such cases lease point them out and they should be fixed. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
