[SOLVED] Finding out the GET

[Azu]

How can I get the get? I know that I can use $_GET[somethingspecific] to retrieve the value of somethingspecific, but what I am trying to do is just retrieve whatever is after the ?
So if someone types in http://www.website.com/?asdf then the asdf would be retrieved. Whatever is it would be retrieved and put into a variable. Please can someone tell me how to do this?

well you can use $_SERVER and there are some options in there... try print_r($_SERVER) and take a look and see if what you need is there.

Or maybe you need to
[code]
foreach($_GET AS $key=>$value){
echo $key . " " . $value;
}
[/code]

The latter would work better.  Below is an example using $_REQUEST, so it will pick up all the values regardless of whether POST or GET was used.

[code]<?php
foreach ($_REQUEST as $k => $v){
  echo "$k - $v<br>\n";
}
?>[/code]

if you want to use $_GET so that you can pass along information via the URL string.... all you'd need is something simple like the following:  www.website.com/somepage.php?var=data

and then the code to grab that data: [code]
if ($_GET['var']) {
 echo $_GET['var']; # would write "data" to the screen
}[/code]

Edit:  Do not use $_REQUEST.  It's a security nightmare -- there are many articles describing reasons not to but the most basic is this.  $_POST is often used when you don't want the user to have the availability to just pass information via the url string.  When you're using $_REQUEST, your $_POST specific code (if you have any) becomes vulnerable to malicious code injection.  Just somethign to think about.

$_REQUEST should be taken into consideration with regards to security, but to say don't use it isn't really helpful.  There are uses for it and if used correctly, can be perfectly secure.

this isn't the place to stand on a soap box but it IS helpful to push people away from using things like $_REQUEST and register_globals because they don't understand what they're doing when they use such superglobals and if they simply take 5 minutes to understand the subtle differences between $_GET and $_POST, they don't need to mess with $_REQUEST.  If a proficient PHP programmer wants to user $_REQUEST and accept the security risks, so be it.  Don't push the noobies towards the easy answer that will lead them and their code to a vulnerable state because they won't know how to "secure" $_REQUEST the way it needs to be.

Fair comment.

your after [color=blue]$_SERVER['QUERY_STRING'];[/color]

Which will return the query string (everything after the ?)...


Also, its not 'programming' unless its compiled, therefore your a proficient PHP [i]scripter[/i].

I thought php was compiled for before it ran.... and if you run a cache system - it stores it in compiled format... So what is really the difference then? manual compiling vs automatic compiling?

I am aware of the differences between the definitions but when you're looking for a job, employers look for PHP [b]Programmers[/b].  I've never seen a category for a job listing for a PHP [i]scripter[/i].

Drifter:  PHP is an interpreted language, not a compiled language, and in that, lies the subtle difference with what hecken was trying to get across.

[drifter]

I think the lines between scripting and programming are not really existant at all - not when you look at everything like php, java, c#, c++ and then try to categories there is not real difference.

[thepip3r]

I'm not trying to argue with you drifter, i was just telling you that in all of the classes I've taken for programming specifically point out that "programming" is used in reference to a compiled language (like C++, etc) and "scripting" is used for an interpreted language (VBScript, Javascript, PHP, KiX, ASP, etc.)  -- Languages like PERL and Java are unique because they can be both compiled or interpreted. Official definitions from Wikipedia:

[url=http://en.wikipedia.org/wiki/Interpreted_language]Interpreted Language[/url]
[url=http://en.wikipedia.org/wiki/Compiled_language]Compiled Language[/url]

[heckenschutze]

C++ is compiled to Machine code, Whereas PHP and Java are compiled to Byte Code and interpreted by a VM...

BIG difference.

Thanks guys :)
