What Can You Do with PHP?

do with PHP.
You can display date, time, and
other information in different
ways.
You can make a survey form and
ask people who visit your site to
fill it out, send emails, save the
information to a file, etc
What Do PHP pages Look Like?
The appearance of an PHP page
depends on who or what is
viewing it. To the Web browser
that receives it, an Active Server
Page looks just like a normal
HTML page. If a visitor to your
Web site views the source code
of an PHP page, that's what they
see: a normal HTML page.
However, the file located in the
server looks very different. In
addition to text and HTML tags,
you also see server-side scripts.
This is what the PHP page looks
like to the Web server before it is
processed and sent in response
to a request.
