PHP - str_replace 在多维数组中不起作用

Question

I have a large array. This is an example part of my array:

13 => [
    'Discount' => '0.00'
    'Total amount' => '50,00'
    'Total Net' => '40,00'
]
14 => [
    'Discount' => '0.00'
    'Total amount' => '20,00'
    'Total Net' => '16,00'
]

I need to convert the commas in the numbers to dots. '50,00' needs to become '50.00' for example. What's an easy way to do this?

Note: I tried $myArray = str_replace(',', ".", $dataArray); but this doesnot work.

Answer 1

You have to loop over the array value's

foreach ($array as $key => $string) {
    $array[$key] = str_replace(',', '.', $string);
}

Answer 2

Since it's a multidimensional array you need to loop nested with both the subarray and the value by reference.
Or have the subarray as the input in the str_replace. (u_mulder)

foreach($arr as &$val){
    $val = str_replace(",",".", $val);
}

var_dump($arr);

You can also add a check to see if there is a comma in the value before you replace.
Not sure if that will make it faster or slower though.

...
if(strpos($val, ",") !== false) $val = str_replace(",",".", $val);
...

I hope this will help you

array_walk_recursive(
    $myarray,
    function (&$value) {
        $value = str_replace(',', '.', $value);
    }
);
