RE: Bug #11962 Updated: eval() doesn't handle multi-dimentional arrays.
OK, so how come it works with 1 dimensional arrays? Surely it would make
sense to make it work with multi-dimensional arrays or not with arrays full
stop?

Your string equals 'echo "$GLOBALS[page][title]";', and RTFM why that
doesn't work.

It appears that eval() does not handle mutli-dimentional arrays properly
e.g. $page[title] = 'Page'; $test = '$page[title]'; If I do: eval( 'echo
"'.$test.'";' ); I get: Page as the output, however if I change $test
to:
$test = '$GLOBALS[page][title]'; then do: eval( 'echo
"'.$test.'";' ); I
get: Array[title] as my output. My best guess for the reason this is
happening is that when eval() does a lookup for a variable in the symbol
table it is going from top to bottom and stops on the first match, no matter
how complete - From this I am assuming that the symbol table would be built
as follows: $GLOBALS $GLOBALS[page] $GLOBALS[page][title] so if eval()
searched from the top then it would find a partial match against
$GLOBALS[page] which is what I think it is doing. A better example:
$page[title] = 'Hello'; $string = '$page[title]'; eval( 'echo
"'.$string.'";' ); echo "<br>\n"; $string =
'$GLOBALS[page][title]'; eval( 'echo "'.$string.'";' );
I hope I make
sense to you, if not then please let me know and I will try and be clearer.
