How does php handle form with multiple selection?

I have a html form which has a select list box from which you can select multiple values because its multiple property is set to multiple. Consider form method is 'GET'. The html code for the form is as follows:

    
    Untitled Document
    
    
    
      

        

          
Multiple Selection  
          

            eleven
            twelve
            thirette
            fourteen
            fifteen
            sixteen
            seventeen
            eighteen
            nineteen
            twenty
          
          
        
        

          
 
          

        
      
    
    
    

I want to display the selected values in select list box on display.php page. So how are the selected values accessed on display.php page using $_GET[] array.

If you want PHP to treat $_GET['select2'] as an array of options just add square brackets to the name of the select element like this:

        twenty
      
      
    
    

      
 
      

    
  

You can iterate it directly like this

foreach [$_GET['select2'] as $value]
    echo $value."\n";

or you can do it like this

$selectvalue=$_GET['select2'];
foreach [$selectvalue as $value]
    echo $value."\n";

You could do like this too. It worked out for me.

     
        Last 1 Week
        Last 2 Week 
        Last 3 Week
         Last 4 Week
          Last 5 Week
           Last 6 Week
    
      

Then take the multiple selection from following PHP code below. It print the selected multiple values accordingly.

$shift=$_POST['selectDuration'];

print_r[$shift];

I fix my problem with javascript + HTML. First i check selected options and save its in a hidden field of my form:

for[i=0; i < form.select.options.length; i++]
   if [form.select.options[i].selected]
    form.hidden.value += form.select.options[i].value;

Next, i get by post that field and get all the string ;-] I hope it'll be work for somebody more. Thanks to all.
