str_replace多维数组中的特定值

Question

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 .
