Answer 1

$animals = array('--Select Animal--', 'Cat', 'Dog', 'Cow');
$selected_key = $_POST['animal'];
$selected_val = $animals[$_POST['animal']];

Use your $animals list to generate your dropdown list; you now can get the key & the value of that key.

Answer 2

you can make it using js file and ajax call. while validating data using js file we can read the text of selected dropdown

$("#dropdownid").val();   for value
$("#dropdownid").text(); for selected value

catch these into two variables and take it as inputs to ajax call for a php file

$.ajax 
   ({
     url:"callingphpfile.php",//url of fetching php  
     method:"POST", //type 
     data:"val1="+value+"&val2="+selectedtext,
     success:function(data) //return the data     
     {

}

and in php you can get it as

    if (isset($_POST["val1"])) {
    $val1= $_POST["val1"] ;
}

if (isset($_POST["val2"])) {
  $selectedtext= $_POST["val1"];
}

Answer 3

You will have to save the relationship on the server side. The value is the only part that is transmitted when the form is posted. You could do something nasty like...

<option value="2|Dog">Dog</option>

Then split the result apart if you really wanted to, but that is an ugly hack and a waste of bandwidth assuming the numbers are truly unique and have a one to one relationship with the text.

The best way would be to create an array, and loop over the array to create the HTML. Once the form is posted you can use the value to look up the text in that same array.

Is there a reason you didn't just use this?

<select id="animal" name="animal">                      
  <option value="0">--Select Animal--</option>
  <option value="Cat">Cat</option>
  <option value="Dog">Dog</option>
  <option value="Cow">Cow</option>
</select>

if($_POST['submit'] && $_POST['submit'] != 0)
{
   $animal=$_POST['animal'];
}
