ARRAYS: display as specific value in a specific "cell" of a multidimentional array?

Joseph_Sliker

This probably belongs in the newbies thread, but I barely understand one dimensional arrays, and two dimensional arrays completely blow me away.

I want the values in a specific column of the two dimensional array to display in an html type table. Sounds like a simple thing, huh? Well, it's got me good and stumped.

Say I've got this data passed in from a prior page:

$2D_ARRAY = array($HTTP_POST_VARS['1D_ARRAY_A'], $HTTP_POST_VARS['1D_ARRAY_B'], $HTTP_POST_VARS['1D_ARRAY_C']);

(the number of elements in each of the 1D_ARRAYS is equal, so it should all work out fine)

I've got a for loop that constructs the rows and puts element in cells:

for ($i=0; $i<count($countervariable); $i++) { 
		print "<tr><td>$SOMETHINGELSE[$i]</td><td>$2D_ARRAY['1'][$i]</td>></tr>";
    }

When I see the page, all I get in the 2D_ARRAY column are array references in the cells (ie. if I leave the ' marks out of $2D_ARRAY['1'][$i], the cells just say "Array[0]", "Array[1]", etc... if I leave them in I just get the [0], [1], etc.

I am actually studying the books on this stuff and am clearly lacking some basic concepts, but the the help I am getting here is a huge help and I really appreciate it. Thanks

$2D_ARRAY declaration is invalid, cause it starts with a number..
count($countervariable) returns 1 if $countervariable is not an array;

...

for ($i=0; $i<$countervariable; $i++)
{
    print "<tr><td>$i</td><td>" . $my_2D_ARRAY['1'][$i] . "</td></tr>\n";
}

Thanks for your reply:

Your point is well taken, I named the variables "2D.." and "1D..." just to keep straight for this example. That was not the problem with my original project code.

So let me try again.

$TWOD_ARRAY = array($HTTP_POST_VARS['ONED_ARRAY_A'], $HTTP_POST_VARS['ONED_ARRAY_B'], $HTTP_POST_VARS['ONED_ARRAY_C']);

The $countervariable is a single dimensional array with the same number of "rows" as $TWOD_ARRAY

hmm...I see you've taken the "count()" out of my loop. I'll give that a try. Thanks.

except it try to remove $TWOD_ARRAY['1'][$i] from string..

Sorry, I did not understand that last message.

gottes_tod

remove your

print "<tr><td>$SOMETHINGELSE[$i]</td><td>$TWOD_ARRAY['1'][$i]</td>></tr>";

for

print "<tr><td>" . $SOMETHINGELSE[$i] . "</td><td>" . $TWOD_ARRAY['1'][$i] . "</td></tr>";

ok??

Hi;

Thanks for your reply. Sorry it took so long to get back to it. By hook or by crook I figured that syntax out myself and now my project is up and running.

Thank you very much!

Joe
