URL variables

[Anonymous]

i am new to PHP totally. All i can do is includes.

what i would like to be able to do is declare a set of variables that have URLs as their values. then use the $HTTP_GET_VARS: thing to get the page and have it display it.

the variables i have no idea how to do but i think i know how to do the get:

$HTTP_GET_VARS['$variable']

am i right?

could someone show me how this works? thanks

To use variables as part of a url you just make up the URL in the following format:
page.php?var1=value1&var2=value2
You might also want to have a look at the urlencode() function too!

On the page accessed using these variables, you can use a multitude of methods.
If the register_globals setting is ON (set to off in PHP 4.2.0 and later by default), you can just call $var1 and $var2.
Otherwise you can use $HTTP_GET_VARS['var1'] and $HTTP_GET_VARS['var2'].
In PHP 4.1.0 and later they've introduced Super Global Arrays, so you can access them by $_GET['var1'] and $_GET['var2']. As these arrays are Super Global, there's no need to declare them as global in functions!

BTW, you're not the same shufty as on a popular DVD forum, are you? :wink:

no im not im afraid.

so how would i declare a load of variables then. like this

$HTTP_GET_VARS['$var, $var2, $var3.....']

this

$_GET['$var, $var2, $var3.....']

or this

$var=./page/page/page.php, $var2=./page/........., $var3=./page/..........

what i am try to achieve is this

http://site.com/page.php?load=a/new/page.php

am i close with that?

What do you mean by declare? PHP isn't like Perl where you have to declare a variable, you can just use it!

To access the variables on the page generated from the 'GET' variables, just use $_GET['varname'] to access the value. All the GET, POST, SESSION, COOKIE and SERVER variables are posted within their own Super Global Arrays accessed by the method $_ARRAYNAME['varName']

Once you've made up your URL as you've written it, on the next page you can use $_GET['load'] which would give you the value "a/new/page.php"
