This is extra code in a Drupal view table template so $row = the content I get..

var_dump($row);

// output:
array(5) { 
    ["field_datum"]=> string(0) "" 
    ["field_werf"]=> string(9) "Comis Cui" 
    ["field_machine"]=> string(17) "Graafmachien D293" 
    ["field_aantal_uren"]=> string(1) "5" 
    ["view_node"]=> string(50) "Bekijk" 
}

$uren = $row['field_aantal_uren'];
var_dump($uren);

// output: string(1) "5" string(1) "7" string(1) "1"

I've tried everything from explode, str_replace, preg_replace to get the 3 strings in an array so I can loop over them them and make a sum. But I can't make it work..

Any suggestions to transform this variable to an array?

you are var_dumping from within a loop. try this:

$uren[] = $row['field_aantal_uren'];

and then OUTSIDE of the loop, you have your array.

echo array_sum($uren);
