[PHP-DEV] RE: Bug #11962 Updated: eval() doesn't handle multi-dimentional arrays.

[Karl Austin]

Hi,

My apologies to you, I have found how to make string substitution of
multi-dimnetional arrays work - however, it was not until I downloaded a
copy of the manual with user contributed errata that I found how to make it
work, something like this really should be included in the actual manual and
not just in the errata.

Thank you,

Karl Austin

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 "\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.
