Study Notes
Server-Side Web Scripting
- Server-side scripting allows for interaction with data resources, validation, data processing, communication, session management, data access control, and user-specific data tailoring.
Architecture
- Server-side scripts are responsible for processing requests and generating responses, including HTML, CSS, and JavaScript.
- Static resources are pre-created and served directly to the client.
- Forms can be used to submit data sent to the server as a GET or POST request.
Server-Side Scripting Languages
- Popular server-side scripting languages include PHP, NodeJS, Java Servlets and JSP, Python, ASP.NET, and Ruby.
HTML Forms
- Forms enable users to submit data using various input elements, such as text fields, checkboxes, radio buttons, and select lists.
- The 'action' attribute specifies the URL for processing the form data.
- The 'method' attribute determines how the data is sent - GET or POST.
- Client-side validation can be done through HTML5 or JavaScript.
- Server-side validation is also crucial to ensure data integrity.
Server-Side Web Scripting with PHP
- PHP is an open-source, server-side scripting language.
- It uses ' <?php' and '? >' as delimiters for PHP code.
- PHP code can be combined with HTML markup.
- Variables are prefixed with '$' (e.g., $name).
- The 'header()' function sets response header information.
- The 'echo' statement outputs text onto the browser, interpreting HTML tags.
- The '.' symbol is the concatenation operator.
- Superglobals, predefined variables, store information about the request, session, cookies, server environment, and other data.
PHP GET
- PHP uses the superglobal array '$_GET' to access the data sent in the URL query string.
PHP POST
- PHP uses the superglobal array '$_POST' to access the data sent in the HTTP message body.
PHP Post Response
- Double-quoted strings in PHP allow variable interpolation and escape sequences.
- Heredoc strings behave like double-quoted strings for multiline text.
- They must start with an identifier prefixed with " <<<" and are concluded with the same identifier on a separate line.
