Answer

Solution:

Add brackets "[ ]" to your select's name:

<select name="allo[]" multiple style='width:163px;'>

Then, you can have all selected values in PHP, like this:

// Here you iterate $_GET['allo'] to get each selected id!
$array_of_ids[] = array();
foreach($_GET['allo'] as $selectedOption)
    $array_of_ids[] = $selectedOption;

print_r($array_of_ids); // This array contains all the selected ids...
