Defining Variables in PHP

[Anon]

Hi Everyone,

I am new to php (real new) and I was hoping someone could tell me how to define a variable at the top of the page or pass it through the URL and then insert it throughout the page

i.e. in vbscript, we add this to the top of the page:

<%Session("city")="ALBANY"%>

and then in the html lower down of the page we would do this:

<b><%=Session("city")%> Hotels</b><p>
blah blah blah

---

I am getting into PHP now and this little bit of code would help me TREMENDOUSLY!

Thanks alot in advance🙂

PHP variables are just defined by using
$var = 'value';
and you usually pass them thru urls using forms and hidden inputs but you can do:
<a href="
http://page.url.com/.../filename.php?var=var_value&foo=bar">...

Wacky

If you're wanting to uses sessions, have a look at http://www.php.net/manual/en/ref.session.php

Your two pieces of code would become

<?php session_register('city');
$city='ALBANY';
?>

and later on...

<?php echo $city ?> Hotels<p>
blah blah blah
