PHP Unit 02: Form Processing and Session Management

What does the 'accept-charset' attribute specify in a form?

What are the three types of arrays used to access form data in PHP?

The value of the query string key 'name' in the URL http://www.darshan.ac.in/course.php?id=4&name=BCA is __________.

Which attribute specifies how the form-data should be encoded when submitting it to the server?

Form Attributes

accept-charset: Defines character encodings for form submission.

- $_REQUEST: Accessible for both GET and POST methods.

Query String

Example URL: http://www.darshan.ac.in/course.php?id=4&name=BCA
Query string: ?id=4&name=BCA
The query consists of:
- Key id with value 4
- Key name with value BCA
Values from the query string can be accessed programmatically using PHP code.
