Multi-Dimensional Arrays Help - And Other Questions on Arrays

[fjm]

that's what I call professional attitude. you're always welcome.



wait ’til you see objects… ;)

Thanks to BOTH of you guys. You guys are fantastic as are alot of the other guys that have helped me so much including Atli and Pbmods. This is a great forum and I sincerley appriciate all the help that you guys continue to extend to me. As if I haven't said it enough. Thanks a lot guys and thanks for sticking with me on this.

Also.. I kind of have a bad habit of putting the cart before the horse.. I have been using objects for about a year now. Unless your talking about something other than class objects that is. :)

I have been using objects for about a year now.

well, I found arrays way easier to understand than objects with all their OOP philosophy attached…

the prospect of fetching DB data into object arrays is always thrilling…

lol.. Ah yes.... record. I have been using that for a little while now. See.. for me, arrays were WAY harder to get a real grasp on. It's kind of like this for me.. I have been programming for about a year and a half now and I feel like I have reached a state where I almost feel embarrassed for not understanding arrays that well. I had an opportunity to talk to another PHP programmer the other day and we were talking about objects and I didn't even break a sweat. But when he started talking about arrays, I just cringed. I have no idea why they have been so hard for me. I do know that having my DBAL with the fetch_array set to BOTH didn't help me because I could never seem to figure out exactly what was going on.

I am not by any means an expert on objects and truly feel that I have grazed the surface but I feel like I write better and cleaner code and that is my #1 priority. The better I can code, the happier I am. :)

Hey Ciary, are you still with me?

[Ciary]

i'm still with you, but i dont have much to say about objects. i dont know much about them.

object are to me what arrays were to you :)

That's cool. I still myself don't fully understand them. I still struggle with objects too. :)

Listen... in your code.. I am getting a foreach error on this line:
foreach($table['Rows'] as $row)

I cannt for the life of me, see it. Can you?

EDIT: Invalid argument supplied for foreach()

[Ciary]

did you correct my 'rows to 'Rows'? if thats not the problem try using $table[1] and see if u still get the problem.

[fjm]

OK, yes, I did originally correct the rows to Rows and that didn't work. I just now tried foreach($table[1] as $row) but now I get an offset error.

[Dormilich]

post the array, maybe we see something…

[Ciary]

what do you get if you replace the foreach with this.

var_dump[$table]

what do you get as output?

[fjm]

Ok here is everything that I have so far.

$pages = array
(
  array
  (
    "Title" => "First page"
    , "Tables" => array
    (
      'a'=>'b',
      array
      (
        "Title" => "First table"
        , "Rows" => array
        (
          'c'=>'d',
          array
          (
            "e"=>"f",
            "Cells" => array
            (
              "Col1"
              , "Col2"
              , "Col3"
            )
          )
        )
      )
    )
  )
);

foreach( $pages as $page )
{
  echo "<h1>" . $page['Title'] . "</h1><br/>";
  foreach( $page['Tables'] as $table )
  {
    echo "<h3>" . $table['Title'] . "</h3><br/>";
    echo "<table>";
    foreach($table['Rows'] as $row)
    {
      echo "<tr>";
      foreach( $row as $cell )
      {
        echo "<td>" . $cell . "</td>";
      }
      echo "</tr>";
    }
    echo "</table>";
  }
}

[Ciary]

if you remove the 'a' => 'b', 'c' => 'd' and 'e' => 'f' it will work

[fjm]

Ok, here's my var_dump:

array(2) {
  ["Title"]=>
  string(11) "First table"
  ["Rows"]=>
  array(2) {
    ["c"]=>
    string(1) "d"
    [0]=>
    array(2) {
      ["e"]=>
      string(1) "f"
      ["Cells"]=>
      array(3) {
        [0]=>
        string(4) "Col1"
        [1]=>
        string(4) "Col2"
        [2]=>
        string(4) "Col3"
      }
    }
  }
}

solution is posted above :)

[fjm]

Got it Ciary. Thanks. I removed them and I no longer have the error but don't have the columns echoing to the browser. Instead, I get the dreaded "Array". :\
