Display values of array of objects

Question

How can I dialplay values of array of objects which is stored into session.

I make like this

//fetch array of countries from db

$countries = array();
    while($row = mysql_fetch_array($result)){

        $country = new Country();

        $country->setCountryName($row['country_name']);
        $country->setCountryNo($row['country_no']);
        $country->setCountryZipCode($row['country_zipcode']);

        $countries[]=$country;
    }

$_SESSION['countries']=$countries;

then display the values of the session like this

<select name="countries" id="countries">
        <?php foreach ($_SESSION['countries'] as $i=>$country ){?>
        <option><?php echo $_SESSION['countries'][$i]=>$country.getCountryName()?></option>   //here's the error
        <?php
        }
    ?>
    </select>

The error occurs when I display the values of session, any help plz?

This error occurs : main() [<a href='function.main'>function.main</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Country" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition in C:\AppServ\www\crm\subpages\SearchCustomer.sub.php on line

I assume the two snippets you posted in your question are from two different scripts. In which file is the Country class defined? You need to include that file in the script that displays the <select> element.

I already include the country file which have the country class, I try to make echo 'hi'; it works and loop as the number of returned countries.

You cannot save objects within session. I'm sorry. But you can store those as array of properties and restore it each time the script starts.
