I am currently working on a small PHP project for my college. I am quit
new to it, so this query might seem trivial to you.
What I am trying to do is use the index.php to act as the front page of
the site, as well as be able to handle queries using the GET method. For
example, http://localhost/index.php?search=somestring should work as
well. That is, there might or might not be a query string. All I want to
know is whether such a query string exists or not. And if yes, what
is(are) the parameter(s) (in this case, search is the parameter).
Thanks in advance.

$_GET is an array which keeps track of query string, not a method.
<?php
if ($_GET)
print_r($_GET);
else
echo "There is no query string";
?>
You could then access individual elements in query string by using
echo $_GET['search'];

Worked, thanks a lot!

A query string is the part of the URL after the question mark.
The syntax is as follows:
<scheme>://<authority><path>?<query>#<fragment>
So for example, in
http://localhost/index.php?search=somestring
the whole "search=somestring" is the query string. How you happen to deal
with it is up to you.
In CGI culture, we normally pass "key=value" pairs separated by an
ampersand (&)

the correct way is to pass them separated by a semicolon (;).
Ampersands are legacy and their usage is deprecated since they have
special meaning in XML and HTML.

My documents validate fine using & in the source. On the other hand,
you are correct. The W3 validators chould maybe throw up a deprecation
warning.

& is the valid way of passing it in.
There are other problems with semi-colons though. You can't use them in
a redirect link because ; is a parameter separater in HTTP headers

That helped a lot! :P

<?

print_r( $_GET );

put that in index.php and call it with different query strings for eg:
http://foobar.com/index.php?a=1&b=2&c=3
and see what you get ;)

I get this when I send a query string like the one you suggested...
Array
(
[a] => 1
[b] => 2
[c] => 3
)
and this when no query string is entered...
Array
(
)
I think Anurag's answer has solved my problem. Thanks to all for your
replies. Will get back to you ppl for any more queries regarding PHP in some
time. :-)

So what does that tell you? You can use this associative array to find
out all the arguments passed to your script using the GET method ;)
