Search and replace inside an associative array

I think this may have been asked before. But I just want a simple solution.

I have an array like this:

  Array (   "name" => "Krish",
            "age" => "27",
            "COD" => ""
        )

I want to replace “” with “0”

Its a multidimentional array. The return value should be array too.

Edit: I tried preg_replace and str_replace. For some reason, these did not work for me.

Answer 1

$array = array(
    "name" => "Krish",
    "age" => "27",
    "COD" => ""
);

you may loop the array and repalce what you want

foreach($array as $key => $value)
{
    if($value == "") $array[$key] = 0;
}

Note:

if you know what key is it you can do it like this

$array['cod'] = 0;
