Read an article: Passing Variables in Links
The key to creating interactivity with PHP is to understand the techniques we can
use to send information about a user’s interaction along with a request for a new
web page. The simplest method we can use to send information along with a page
request is to use the URL query string.

Watch a video: htmlspecialchars7.
Read an article: Passing Variables in Forms
Using links to pass variables between pages is all well and good, but we still have
yet to achieve our goal of true user interaction, where the user can enter arbitrary
information and have it processed by PHP. To enable the user to type in a value,
we’ll need to use a HTML form.
8.
Join a Discussion: Pass a variable to a third page
Most of the examples we looked at today involved passing a variable from one page
to another. But what if that second page contained a link or a form that submitted to
a third page, to which you also wanted to pass the same value? If you’re up for the
challenge, try getting an example of this working, and share your solution in the
private course forum!
