URL parameters allow passing information between pages via a URL. In this video, you will learn how to add parameters to the URL and how to use PHP to read those parameters.
- [Narrator] In this movie, we'll learn send…a value from one page to the next by using URL parameters.…This can also be referred to as query parameters.…The URL parameters are the part of the URL…which comes after the question mark.…The format is always name of the parameter,…then an equal sign and then the value of the parameter,…so here we have page equals two.…URL parameters generally modify…the behavior of the code used for the response,…so, in this example, the same PHP code…would be run, but its behavior would probably be…modified, so that it return the second page of results.…
You can send more than one URL parameter…by using an ampersand in-between them.…Here you I have category equals seven and page equals three.…If you surf around on sites like Google and Amazon,…you'll see many examples of URL parameters being used.…URL parameters are useful, because they allow us…to pass data from one page to another via links.…When a new page request is received,…PHP is automatically going to take all of those URL parameters…
