How can the use of $http_response_header in PHP scripts affect the handling of cookies when integrating APIs?

When using $http_response_header in PHP scripts, it can affect the handling of cookies when integrating APIs because it may not capture the Set-Cookie header properly. This can lead to issues with maintaining session information and authentication tokens. To solve this problem, you can use the curl_setopt() function in PHP to explicitly capture and handle cookies in the API response. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
$response = curl_exec($ch);

// Extract cookies from response headers
preg_match_all('/^Set-Cookie:\s*([^;]*)/mi', $response, $matches);
$cookies = array();
foreach($matches[1] as $item) {
    parse_str($item, $cookie);
    $cookies = array_merge($cookies, $cookie);
}

// Use cookies as needed for subsequent API requests
// Example: curl_setopt($ch, CURLOPT_COOKIE, http_build_query($cookies));

curl_close($ch);
