Q:

Handle number in string php (Part2)

this is my problem 1 here: Handle number in string PHP . I solved it.
Now, i see new problem, you can see the picture:

I want to get only number, not date (500000 and 200000) and sum it.
This is my code without date:
$total= 0;
    $ex = explode(' ',$_POST['txtSalary']);
    function total($ex) {
        global $total;
        return $total+=$ex;
    }
    array_map('total',$ex);
    echo $total."<br/>";

I try so much but no result, hope you can help me. Thank you!

A:

I assume that your $_POST['txtSalary'] look like below:-
$_POST['txtSalary'] = '-27/07/2016: 5000000
-01/08/2016: 2000000';

So do like below:-
<?php

$_POST['txtSalary'] = '-27/07/2016: 5000000
-01/08/2016: 2000000';

$array = explode(PHP_EOL, $_POST['txtSalary']);
print_r($array);

$sum = 0;
foreach($array as $arr){
   $sum += explode(': ',$arr)[1];
}

echo $sum;
