Read Value from URL in PHP

I have a link on Home Page say for eg

<a href="count.php?id=<开发者_运维知识库?php echo $row['ID']; ?>&desc=<?php echo $row['PRO']; ?>" name="abc<?php $i; ?>">**Home**</a></li>

Once click on Home Link provided above it goes to next page that is

http://abb/MyWeb/pr/arro/count.php?id=4&desc=It%20isavailable

Now I want to read value from URL

id=4 and desc=it is available

and I want to store it in variable

$idenity = id1 ( store the id from url to variable )

Is this what you want?

$identity=$_GET['id'];

$identity = $_GET['id'];
$desc = $_GET['desc'];

Make sure that you filter the contents of the $_GET array to avoid vulnerabilities. For instance, if id is supposed to be a number, force it:

$identity = (int)$_GET['id'];
