Question

I have got a 2d array called $myarray, and when I using var_dump($myarray), it gives me the following:

  array(4) { [0]=> array(2) { [0]=> string(3) "EUR" [1]=> string(9) "43,543.23" } [1]=> array(2) { [0]=> string(3) "USD" [1]=> string(9) "13,432.34" } [2]=> array(2) { [0]=> string(3) "GBP" [1]=> string(8) "3,432.21" } [3]=> array(2) { [0]=> string(3) "CAD" [1]=> string(8) "2,321.34" } } 

But I want the output to be the follwing format:

Totals
GBP 3,432.21
USD 13,432.34
EUR 43,543.23
CAD 2,321.34

I assume that I need to sort the array to be:

GBP 3,432.21
USD 13,432.34
EUR 43,543.23
CAD 2,321.34

and add “Totals”, “” into the array, I might be wrong, soanybody could help me with that, any help will be greatly appreciated! I want it to be done in a programmatic way! how to sort the array $myarray to the expected output?

Answer 1

Firstly, do not add anything non-data related to your array. You the string “Totals” should not be included in your array. If you just want the output, I suggest a better way to solve your problem :

<?php 
   class MyMoney {
      var $type;
      var $value;

      public function __toString() {
         return $type."  ".$value."\n";    
      }
   }

   $output="Totals:\n";
   // $data is an array of MyMoney objects
   foreach( $entry in $data ) {
      $output.= (string) $entry;
   }

   dump($output);

I hope this helps.
