Which methods are needed when passing values through a form or an URL in PHP?
If we would like to pass values through a form or an URL then we need to encode and decode them using htmlspecialchars() and urlencode().
A webform when the method is set to GET method submits the values through URL. So we can use one form to generate an URL with variables and data by taking inputs from the users. The form will send the data to a page within the site or outside the site by formatting a query string.
The htmlspecialchars function in PHP is used to convert 5 characters into corresponding HTML entities where applicable. It is used to encode user input on a website so that users cannot insert harmful HTML codes into a site.
The urlencode() function is an inbuilt function in PHP that is used to encode the URL. This function returns a string which consists of all non-alphanumeric characters except -_. and replace by the percent (%) sign followed by two hex digits and spaces encoded as plus (+) signs.
