I can not assign the value recived from $_GET[] to a variable
<p>I am trying to pick the id using the <code>$_GET[]</code> and assign it to a variable however it does not work. when i try to echo <code>$_GET[]</code> directly it works fine the ID is displayed on the page, however when i assign it to a variable and try to echo it, it wont work. for example this wont work: </p>

<pre><code>$sel_hotel = $_GET[];
echo $sel_hotel; 
</code></pre>

<p>The code looks fine there is no any problem with it but it just don't pass that value to the variable i believe there may be something wrong with my php.ini file but i am not sure. i am using PHP Version 5.4.3. Please Help . Thank you very Much </p>

<pre><code>&lt;?php 
if(isset($_GET['hotl'])){
 $sel_hotel = $_GET['hotl']; 
 $sel_hotel ="";
 echo   $sel_hotel;
}elseif(isset($_GET['room'])){
 $sel_room = $_GET['room'];
 $sel_room ="";
 echo $sel_room;
}else{
$sel_hotel ="";
$sel_room ="";
}
echo  $sel_hotel;
