[SOLVED] array_sum ignores commas

[xiao]

The array_sum function seems to ignore commas in numbers, so if I do for example:

1,5 + 2,9 + 3,7 it returns 6 instead of 8,1

Is there a way to fix this?

Or do I really have to replace all commas with dots, do array_sum and replace the dot with a comma again?  ???

Why are you using commas in the first place? Use the dot, that's why it's called a decimal point.

[xiao]

Because we use a comma in this country.

Gah, apologies, totally forgot about the math punctuation deferences.

 

Yes you'll probably have to change it to a period.

you can just make your own function. This one will add up the numbers for you, just put the number in an array.

 

<?php
function add_numbers($array){
  if(is_array($array)){
    foreach($array as $n){
    $numbers[] = str_replace(",", ".", $n);
    }
  $total = number_format(array_sum($numbers), 2, ',', ' ');
  } else {
  $total = "Numbers should be in an array";
  }
return $total;
}

$numbers = array("5,7", "5,9", "5,8");

echo add_numbers($numbers);
?>

I know this is marked solved, but you can do the same thing using the array_map() function:

<?php
function comma_dot($str) {
return(str_replace(',','.',$str));
}

$numbers = array("5,7", "5,9", "5,8");
echo number_format(array_sum(array_map('comma_dot',$numbers)),2,',',' ');
?>
