 <select name="pcity" id="pcity" multiple="multiple">

<?php
$pcitylist = array('Andaman and Nicobar' => array('North and Middle Andaman',
    'South Andaman', 'Nicobar'), 'Andhra Pradesh' => array('Adilabad', 'Anantapur',
    'Chittoor', 'East Godavari', 'Guntur', 'Hyderabad', 'Kadapa', 'Karimnagar',

    'Changlang', 'East Kameng', 'Lohit', 'Lower Subansiri', 'Papum Pare', 'Tirap',
    'Dibang Valley', 'Upper Subansiri', 'West Kameng'));
foreach ($pcitylist as $pcitylist1) {
    echo '<option value="' . $pcitylist1 . '"' . (isset($_POST['pcity']) && $_POST['pcity'] ==
        $pcitylist1 ? ' selected' : '') . '>' . $pcitylist1 . '</option>';

<select> <optgroup>Andaman and Nicobar</optgroup> <option>Adilabad</option> <option>Anantapur</option> </select> Syntax is not correct. – Pankit Kapadia Dec 14 '12 at 7:18
@PankitKapadia you should show him the correct syntax. – beerwin Dec 14 '12 at 7:37

foreach ($pcitylist as $key => $pcitylist1)
{
      echo '<optgroup label="'.$key.'">';
      foreach ($pcitylist1 as $finalCity) {
          echo '<option value="' . $finalCity . '"' . (isset($_POST['pcity']) && $_POST['pcity'] == $finalCity ? ' selected' : '') . '>' . $finalCity . '</option>';
      }   
      echo '</optgroup>';
}

The $key holds the optgroup label. This will work with your array.

It is an multidimensional array... use one more for loop inside ur for loop and u will get the ouput..

Try the following..

foreach ($pcitylist as $key => $pcitylist1)
{ 
      foreach ($pcitylist1 as $finalCity) {
          echo '<option value="' . $finalCity . '"' . (isset($_POST['pcity']) && $_POST['pcity'] == $finalCity ? ' selected' : '') . '>'.$key . $finalCity . '</option>';
      }    
}
