$value = $_POST['car']; //assuming coming from form

$cars = array ("Volvo","BMW","Toyota");
$nums = array ("200","300","400");

$index = array_search($value, $cars);
$num = $nums[$index];

echo $value . ': ' . $num; //test

I tried to expand your code on a query..



    $prod_id = $_POST['prod_id'];
    $value = $_POST['sizeStatus']; //assuming coming from form

     $sql1 = "select * from tbl_product where prod_id = $prod_id";//SQLquery

    $result1 = mysqli_query($con,$sql1);
    $row = mysqli_fetch_array($result1);

    $sizes = $row['sizes'];//assuming coming from database : 1, 2, 3
    $colour = $row['colors'];//assuming coming from database : red, blue, pink 

    $arraySize = explode(',',$sizes);
    $arrayColour = explode(',',$colour);
    $index = array_search($value, $arraySize);
    $num = $arrayColour[$index];
    echo $value . ': ' . $num; //test 


<!---// FORM  //-->
<form method="post" action=""> 
        $sql = "select * from tbl_product where prod_id = 468"; //SQLquery
        $result = mysqli_query($con,$sql);
        $row = mysqli_fetch_array($result);
        $prod_id = $row['prod_id'];
        $sizes = $row['sizes'];

        echo '<input type="hidden" name="prod_id" value="'.$prod_id.'">';
        $temp = explode(',',$sizes);
        echo "<select name='sizeStatus'>";
        foreach($temp as $size){
        echo "<option>".trim($size)."</option>";
        echo "</select>";

<input type="submit" name=" submit">

the SIZE VALUE was right .. but the COLOUR VALUE is always RED .. why please help ..

why are you exploding sizes? How do you have the size column defined? Try not to mix php with html if you can.

<form method="post" action="">
    $sql = "SELECT * FROM tbl_product WHERE prod_id = '468'";
    $results = mysqli_query($con, $sql);

    $row = mysqli_fetch_array($results);

    $sizes = explode(',',$row['size']);

<input type="hidden" name="prod_id" value="<?php echo $row['prod_id']; ?>" />

<select name="sizeStatus">
<?php foreach($sizes as $size): ?>
    <option value="<?php echo trim($size); ?>"><?php echo trim($size); ?></option>
<?php endforeach; ?>
<input type="submit" name=" submit">

Also give your option a value like above.
