如何根据PHP数组的长度声明多个会话变量

session_start();
$imgList = $_REQUEST['imgList']; //comes through post (jquery)
$i = 0;
$a = explode(',', $imgList); 
$abc = count($a);

for ($e = 0; $e < $abc; $e++)
{
  echo $_SESSION['c+$i']=$a[$e];
  $i++;
}

echo $_SESSION['c+$i']; //this returns the last value
echo count($_SESSION['c+$i']); //returns only length 1
echo count($i); // returns only length 1

I don't know why more than one variable are not initilizing. can anyone please tell me about htis problem or fix this.i"ll be very thankful to you for this favor

    Change your code completely like below:-

    session_start();
    $_SESSION = array();
    $imgList = $_REQUEST['imgList']; //comes through post (jquery)
    $a = explode(',', $imgList); 
    $_SESSION['c'][] = $a;
    print_r($_SESSION['c']);
    

    Now on other page if you need to access this SESSION data, do like below:-

    session_start();
    print_r($_SESSION['c']);
    foreach($_SESSION['c'] as arr){
      echo $arr."
    ";
    }
