In what situations can errors related to setting cookies in PHP occur when moving scripts to a new server?

Errors related to setting cookies in PHP when moving scripts to a new server can occur due to differences in server configurations, such as the domain or path settings. To solve this issue, ensure that the domain and path parameters are correctly set when calling the setcookie() function in PHP.

// Setting a cookie with correct domain and path parameters
setcookie("cookie_name", "cookie_value", time() + 3600, "/", "example.com");
