    The is_server_error() function in WordPress is a utility function used to determine if a specific HTTP status code is categorized as a server error. Server errors are in the range of 500-599, according to the HTTP status code definitions. This function is particularly useful when handling HTTP responses.

    Function Definition

    is_server_error( $sc )
    
    • Parameter:

      • $sc (int): The HTTP status code to check.
    • Return:

      • (bool): Returns true if the provided status code is within the server error range (500-599); otherwise, it returns false.

    Sample Usage

    Here's an example of how you might use is_server_error() in a WordPress context:

    $status_code = http_response_code(); // Assume this returns an HTTP status code
    
    if ( is_server_error( $status_code ) ) {
        // Handle server error
        echo "A server error occurred. Please try again later.";
    } else {
        // Handle non-server error scenarios
        echo "The request was processed successfully.";
    }
    

    In this example, http_response_code() is used to get the current HTTP status code of the response. is_server_error() is then called with this status code. If the function returns true, it means the status code indicates a server error (e.g., 500 Internal Server Error), and the script handles this scenario accordingly. If the function returns false, it's an indication that the status code is not in the server error range, and a different response is provided.
