dynamic variable variable with while loop

Question

i have following while

while($rs=mysqli_fetch_array($row))
{
 }

in each while execution there is one column which will have some ID lik 5 , 6 7, 8

ID  Name    Intake  division_no      
1   5       1       2    
2   6       4       5

i have some varible name like txtin5, txtin6

while looping in while i want to automatic assign intake value to that variable for ex in this case

        $txtin5 = 1
        $txtin6 = 4

i used this

      $spvar = "txtin" ;
 $i=5;
    while {
    $$spvar.$i = rs['Intake']; 
 $i++;
    }

i know this is wrong , but anyone could tell me the right way

Here's how you do variable variables in PHP:

${$spvar.$i} = $rs['Intake'];

However, I recommend that you avoid the need for this. Instead of variables $txtin5 and $txtin6, why not make $txtin be an array, so you can use $txtin[$i]?

You can use arrays instead of what you did. Handling array is quite simple and easy. SO your code will look like:

    while {
    $spvar[] = rs['Intake']; 
     }

ANd if you want to have a associative array you can use:

   $i=5;
    while {
    $spvar[$i] = rs['Intake']; 
 $i++;
    }
