How can issues with data integrity and escape characters be addressed when using CSV or JSON formats for storing arrays in PHP?

To address issues with data integrity and escape characters when storing arrays in CSV or JSON formats in PHP, you can use built-in functions like `fputcsv()` for CSV files and `json_encode()` for JSON files. These functions handle escaping special characters and ensure data integrity when writing arrays to files. 

// Example for storing an array in a CSV file using fputcsv()
$data = ['John,Doe', 'Jane "Smith"'];
$fp = fopen('data.csv', 'w');
foreach ($data as $fields) {
    fputcsv($fp, [$fields]);
}
fclose($fp);
```

```php
// Example for storing an array in a JSON file using json_encode()
$data = ['John,Doe', 'Jane "Smith"'];
$jsonData = json_encode($data);
file_put_contents('data.json', $jsonData);
