I'm not getting an undefined variable error, but I may just not have my error reporting set high enough. > This is PHP 4.0.4-dev, CVS from about 20 minutes ago.

Either way, the answer will > make it into the manual. :) Here's what I came up with, running 4.0.1pl2.. $foo = array( 'bar' => array( 'name' => 'Bill' ) ); $arr = 'foo'; $ind = '[bar][name]'; // This is undefined echo ${$arr . $ind}; ${$arr . $ind} = 'Another value'; // Now it's defined echo ${$arr . $ind}; So does this mean I just created a string variable named $foo[bar][name] If I do a foreach ($GLOBALS as $key => $val) echo "$key\n" foo[bar][name] does indeed show up. I wonder if that should be allowed? Matt
