Hi,
Your select is not an array, but a simple value, since only 1 can be
selected.
So if you want to know what was selected, just use:
<select name="OS" size="5">
and from PHP: $_GET["OS"]
Of course this means the method of the form was GET and not POST, in which
case you should use $_POST["OS"]
I think you are confusing checkboxes with select.
For checkboxes you can use:
<input type="checkbox" name="myval[]" value="1">1<br>
<input type="checkbox" name="myval[]" value="2">2<br>
<input type="checkbox" name="myval[]" value="3">3<br>
then from PHP:
$myvalArr = $_POST["myval"];

By the way, I think you're missing the attribute MULTIPLE from the select if
you want to be able to select multiple items. It should be
<select name="OS[]" size="5" multiple>
or if you're using xhtml,
<select name="OS[]" size="5" multiple="multiple">

or if you're using xhtml,

i did set multiple, and the foreach and the echo result is:
if all the items in the list are selected :
0: 1
1: 2
2: 3
3: 3
if second selected then the echo will be: 0: 1
ok, i can work this way, but can it echo values i mean selected string,
like Windows, Linux, ... , not 0:1, 0:2, etc ...
is it possible ?
eccept if ... or switch condition
foreach($_GET['OS'] as $i => $val)
if($i == 0 && $val == 1)
echo "Windows <br>";
if($i == 0 && $val == 2)
echo "Linux <br>";
... etc
this is too complicated, what if i have 40 items in the list :) | |

Why are you using 1, 2, 3, etc. when you want Windows, Linux, etc.?
Perhaps this little example will help:
<?php
if( isset($_GET['OS']) ) {
foreach( $_GET['OS'] as $key => $value) {
printf("Selected %s<br>\n", $value);
}
}
?>
<html>
<head></head>
<body>
<form action="test.php" method="GET">
<select name="OS[]" size="5" multiple>
<option>Windows</option>
<option>Linux</option>
</select>
<input type="submit">
</form>
</body>
</html>

Looks like you're overcomplicating things.
Just change the options to pass the string instead of an index (unless you
need the indes for something else):
<select name="OS[]" size="5" multiple="multiple">
<option value="" selected>Please select one or more...</option>
<option value="Windows">Windows</option>
<option value="Mac OS X">Mac OS X</option>
<option value="Linux">Linux</option>
</select>
Then
$myarray = $_GET['OS'];
will then give you an array of the selected Strings
