A little simple help with PHP - Need to post not alert

mibearings

Hello,
I'm a little of a newbie with PHP, but I have basic understanding.
At the end of my page, I have the code

<script type="text/javascript">
alert($_GET['query']);
</script>

You can see, when you go to http://mibearings.com/search/search.php?query=Chevy&search=1
It alerts the user that they have keyed in "Chevy" if you search something else, it will alert the user of whatever you type in.
I would instead like it to just post it. so where i put the code,

<script type="text/javascript">
alert($_GET['query']);
</script>

I get the query text only. I'm sure it is as simple as replacing the "alert" function with another function, but I do not know what function to use.
Thanks ahead of time!

<?php
echo $_GET['query'];
?>

will output

Chevy

in a .php file from the url ..?query=Chevy..

Thank You Very Much!
It worked like a charm!

So for anyone who finds this page via google

to pull a variable out of the URL such as http://mibearings.com/search/search.php?query=Chevy&search=1
To pull the word Chevy out,
you will need the code

<script type="text/javascript">
window.$_GET=(function(){
var get_array=new Object();
if(!location.search)return get_array;
var p=location.search.replace(/\+/g,"%20").substr(1).split("&"),l=p.length;
for(var i=0,t;i<l;i++){
t=p[i].split("=");
if(!t[0])t[0]="";
if(!t[1])t[1]="";
t[0]=decodeURIComponent(t[0]);
t[1]=decodeURIComponent(t[1]);
get_array[t[0]]=t[1];
}
return get_array;
})();
</script>

and where ever you place

<?php echo $_GET['query']; ?>

you will be returned with Chevy, or whatever your text is after =
To change what you are pulling the text from simply replace the query with whatever you need.
thanks again coldwerturkey

no. you don't need to use javascript to assign a $_GET var in php - infact I'm 93% sure you can't - it's one of php's reserved variables and defines it automatically. (fyi: note the use of htmlspecialchars() in the php.net example)
