What function in PHP can be used to search and replace a specific string in an array obtained from a database?

To search and replace a specific string in an array obtained from a database in PHP, you can use the array_map() function along with a callback function that performs the search and replace operation on each element of the array. The callback function can use the str_replace() function to replace the specific string with the desired replacement value. 

// Assuming $data is the array obtained from the database
$search = 'old_string';
$replace = 'new_string';

// Define a callback function to perform search and replace
function searchAndReplace($item) {
    global $search, $replace;
    return str_replace($search, $replace, $item);
}

// Use array_map() to apply the callback function to each element of the array
$updated_data = array_map('searchAndReplace', $data);

// $updated_data now contains the array with the specific string replaced
