Handle number in string PHP

Question

I have a text area, it include string and number.

I want to sum 3 record into a text like this

I try to show you my stack, hope you can help me. Thank you!

First i want comma and dot, but now, only comma is enough for me — XCode2015, Jul 26 '16 at 08:35
Maybe you should just use 3 different input elements instead of a textarea. — Adam, Jun 30 '19 at 08:15

With a little regular expression

$s = "xxx = 230.5
bbb = 490.3
ccc = 3.948";

preg_match_all('/[,\.\d]+/', $s, $match);
print_r($match);
exit;

Result

Array
(
[0] => Array
    (
        [0] => 230.5
        [1] => 490.3
        [2] => 3.948
    )

)

Please regard: if you use comma and dot, you'll have to prepare the values for a valid floating point format.

I dont know, how to do that this would work with comma, but this code

If(isset($_POST['test'])) { //test is my textarea name
    $total = 0;
    $ex = explode(' ',$_POST['test']);
    function total ($ex) {
        global $total;
        return $total+=$ex;
    }
    array_map('total',$ex);
    echo $total;
}

Worked well, when you write normal integer without anything (for example - 3500) and double with a dot (for example - 3.5). I think this function is good enough to use it

Yeah, your way work so good. But with comma and dot will be float ~^^~. Maybe i must prepare for a valid floating point format, Thank you! – XCode2015 Jul 26 '16 at 08:45
I think both double and float are with dot :D if you meant that – Danielius Jul 26 '16 at 08:49
