Multi-dimensional arrays

cjliu42

Hi All,

I am really struggling with sorting the multi-dimensional array sort, so would be grateful if u can help.

From the php.net it gives the following example:

$data_array["FirstName"][0] = "John";
$data_array["FirstName"][1] = "Marta";
$data_array["FirstName"][2] = "Trent";
$data_array["LastName"][0] = "Lin";
$data_array["LastName"][1] = "Tremblay";
$data_array["LastName"][2] = "Nguyen";
$data_array["Extension"][0] = 5555;
$data_array["Extension"][1] = 2222;
$data_array["Extension"][2] = 3333;

and wanted to sort by the column, "Extension", in ascending order to output the following:

FirstName LastName Extension
Marta Tremblay 2222
Trent Nguyen 3333
John Lin 5555

use:

array_multisort($data_array["Extension"], SORT_NUMERIC, SORT_ASC, $data_array["FirstName"],$data_array["LastName"]);

How can I display the array?

FirstName LastName Extension
Marta Tremblay 2222
Trent Nguyen 3333
John Lin 5555

How I setup my arrays normally is:-

array[1]["string"]
array[2]["string"]
array[3]["string"]

But given the example of the above array_multisort(), I have to change my array setup. Can anyone give me an example.

Thanks..

echo "<table><tr><td>FirstName</td><td>LastName</td><td>Ext.</td></tr>";
$x=0;
while ($x<count($data_array['FirstName'])) {
     echo "<tr><td>".$data_array['FirstName'][$x]."</td>";
     echo "<td>".$data_array['LastName'][$x]."</td>";
     echo "<td>".$data_array['Extension'][$x]."</td></tr>"; 
     }

Functional. Elegant? dunno....

Well, set $x=1 if that's where you start (be forewarned PHP starts at zero) and loop in a similar fashion. Depending on the content of your arrays, though, I'd say that the other construction is a bit more logical...not enough info to decide that.

HTH,
