Here is my code
PHP
<?php
    $count1 = $obj->getDatef();
    $as1 = $count1 + 6;
    $startdate = date('d/m/Y', strtotime($count1 . ' days'));
    $enddate = date('d/m/Y', strtotime($as1 . ' days'));
    echo "<script type='text/javascript'>";
    echo "alert('Current Timesheet period($startdate (Mon) ~ $enddate (Sun)) of 
              $pcode has been successfully Updated....!')";
    echo "</script>";
    echo "<script type='text/javascript'>";
    echo "window.location='my_tm.php'";
    echo "</script>";
?>
Here it have to print like this.....
Current Timesheet period
$startdate (Mon) ~ $enddate (Sun) of $pcode
has been successfully Updated....!
