Solution Ch0cu3r Posted December 3, 2013 Solution Share Posted December 3, 2013 (edited) make $_SESSION["odd"] and $_SESSION["even"] arrays. You can then use array_sum to add up the odd/even numbers together. To list the numbers you can use implode <?php // reset session if(isset($_POST['reset'])) { session_destroy(); unset($_SESSION); } session_start(); $_SESSION["number"] = rand(1,10); // set odd and even sessions to array if(!isset($_SESSION["odd"]) || !isset($_SESSION["even"])) { $_SESSION["odd"] = array(); $_SESSION["even"] = array(); } if(isset($_GET["check"])) { if ($_SESSION["number"] %2 == 0) { $_SESSION["even"][] = $_SESSION["number"]; // even number to array } else { $_SESSION["odd"][] = $_SESSION["number"]; // odd number to array } } $_SESSION["sum"] = array_sum($_SESSION["odd"]) + array_sum($_SESSION["even"]); // add up the odd and even number array's ?> <body> <form action="" method="post"> ODD number: <?php echo implode(',', $_SESSION["odd"]); /* list odd numbers */ ?> <br /> EVEN number: <?php echo implode(',', $_SESSION["even"]); /* list even numbers */ ?><br /> SUM of all the numbers that have appeared:<?php echo $_SESSION["sum"];?><br /> <input type="submit" name="check" value="submit" /> <input type="reset" name="reset" value="Reset" /> </form> </body> Edited December 3, 2013 by Ch0cu3r Quote Link to comment Share on other sites More sharing options...
computernerd21 Posted December 4, 2013 Author Share Posted December 4, 2013 thanks it works but how do i make it in a way that it doesnt list every number and for it to replace the old number with the new one? Quote Link to comment Share on other sites More sharing options...
