Bug description: eval() doesn't handle multi-dimentional arrays.
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.
