str_replace多维数组中的特定值

I would like to replace the , with . in some Keys like [Price] for instance.

Given this array:

Array
(
    [0] => Array
        (
            [Product line] => Misc
            [Seller] => aaa.com
            [Tracking ID] => bbbb
            [Date shipped] => October 23, 2015
            [Price] => 60,43
            [Referral fee rate] => 3,00%                
            [Quantity] => 2
            [Revenue] => 120,86
            [Earnings] => 3,62
            [Sub Tag] => xxxx
        )

    [1] => Array
        (
            [Product line] => Misc
            [Seller] => aaaa.com
            [Tracking ID] => bbbb
            [Date shipped] => October 23, 2015
            [Price] => 9,34
            [Referral fee rate] => 6,96%                
            [Quantity] => 1
            [Revenue] => 9,34
            [Earnings] => 0,65
            [Sub Tag] => xxxx
        )
)

And the following function:

function str_replace_specific_value($sSearch, $sReplace, &$aSubject){
    foreach($aSubject as $sKey => $uknValue) {
        if(is_array($uknValue)) {
            foreach($sKey as $fKey => $fuknValue) {
                $uknValue['Price'] = str_replace($sSearch, $sReplace, $fuknValue);
            }
        }
    }   
}

Can someone help me please? I tried a couple of things but can't get it to work.

    You can iterate through each element of associative array using array_walk_recursive function.

    Here $result is your input array.

    array_walk_recursive($result, 'replacer');
    
    /**
     * Replace comma with dot from 'Price' element of associative array.
     * This function call recursively
     *
     * @access public
     *
     * @param string|int|null $item
     * @param string $key
     * @return void
     */
    public function replacer(& $item, $key)
    {
        if ($key == 'Price') {
            $item = str_replace(",", ".", $item);
        }
    }
    

    var_dump($result) to check the output after replacing , with .

    Change the main array, like this:

    function str_replace_specific_value($sSearch, $sReplace, &$aSubject){
        foreach($aSubject as $key => $sub_array) {
            if(is_array($sub_array)) {
                foreach($sub_array as $sub_key => $sub_value) {
                    $sSubject[$key][$sub_key] = str_replace($sSearch, $sReplace, $sub_value);
                }
            }
        }   
    }
    

    In casu you wanted to do only on a set of keys, you would need to declare those keys and use this other function:

    $keys_to_be_replaced = ['price','whatever'];
    
    function str_replace_specific_value($sSearch, $sReplace, &$aSubject, $keys_to_be_replaced){
        foreach($aSubject as $key => $sub_array) {
            if(is_array($sub_array)) {
                foreach($sub_array as $sub_key => $sub_value) {
                    if(in_array($sub_key,$keys_to_be_replaced))
                      $sSubject[$key][$sub_key] = str_replace($sSearch, $sReplace, $sub_value);
                }
            }
        }   
    }

    You can try this:

    $arr[0] = array("price" => "60,53");
    $arr[1] = array("price" => "9,34");
    
    foreach ($arr AS $key => $value) {
       $arr[$key]["price"] = str_replace(",", ".", $arr[$key]["price"]);
    }
    echo "<pre>";
    print_r($arr);
    

    Output:

    Array
    (
        [0] => Array
            (
                [price] => 60.53
            )
    
        [1] => Array
            (
                [price] => 9.34
            )
    
    )
