    How do you use sessions so that an array becomes the new array when page refreshes?

    in PHP Coding Help

    Posted

    I'm trying to create a code that moves a string array A B C D E around based on the amount specified entered into a field in a form and the direction which is also entered into the form. What I want to do is to make the $newarray equal $array when the page is refreshed and the submit button is hit again. That way A B C D E when moved LEFT by 1 will be B C D E A and then if RIGHT and 2 is entered, you will see E A B C D. I've been struggling to get session working and just ended up more lost. Here is the code I got so far. I would greatly appreciate any help with this.

    <html>
        
       
    <div style="border:1px solid black;font-weight:bold;">
         <div style="border:none;">A B C D E</div>
        
        <form method="POST">
            <input type="text" name="thebutton"/>      
        
         <input type="text" name="offset"/>
        
            <input type="submit" value="SUBMIT"/>
               
        
        </form>
        
        </div>
           
    <?php
    session_start();
     
    if (isset($_POST["offset"], $_POST["thebutton"])) {
     
    $shift=$_POST["offset"];
    $direction=$_POST["thebutton"];
    $counter=0;
    $array=array('A','B','C','D','E'); 
     
     
    if ($direction=="LEFT"){
        for($i=$shift; $counter+$shift<5; $i++,$counter++){
           
            $newarray[$counter]=$array[$counter+$shift];
           
            
        }
        
    for($j=0; $j<$shift; $j++){
            $newarray[$counter + $j]=$array[$j];
           
        }
        
    }
    if ($direction=="RIGHT"){
        for($counter=0,$k=5-$shift; $counter<$shift; $counter++){
           
            $newarray[$counter]=$array[$counter+$k];
           
            
        }
        
    for($j=0; $j<5-$shift; $j++){
            $newarray[$counter + $j]=$array[$j];
           
        }
        
    }
     
     
    echo $newarray[0];
    echo $newarray[1];
    echo $newarray[2];
    echo $newarray[3];
    echo $newarray[4];
     
     
    } 
     
    ?>       </html>
