如何在php循环结束后将值存储到变量，以便我可以在其他查​​询中使用该变量？

Question

$efind = $_SESSION['email']; 
require('mysqli_connect.php'); 

$sql = "SELECT userid,fname,lname,email,phone,adds FROM userst where email ='$efind'"; 
$result = mysqli_query($dbcon, $sql); 

while($row = mysqli_fetch_assoc($result)) 
{ 
    // What to write here ? 
} 

我希望存储userid，fname，lname，email，phone，adds是从循环中取出，但是当我附和变量，他们没有任何价值。

使用此

$sql = "SELECT userid,fname,lname,email,phone,adds FROM userst where email ='$efind'"; 
      $result = mysqli_query($dbcon, $sql); 
      $firstName = ''; 
      $lastName = ''; 


      while($row = mysqli_fetch_assoc($result)) 
      { 
       $firstName = $row['fname']; 
       $lastName = $row['lname'];; 
      }
