在While循环中重置计数器

I would like to reset counter in the following loop. Have no idea how to do it

$j = 1; 
while($row = mysqli_fetch_array($check)) { 
$value = $row['tmpi'];

$calculate = mysqli_query($link,"SELECT * FROM tmpi_db WHERE  tmpi_id = '".value."'");  

$action = mysqli_num_rows($calculate); 


if($j == $action) {

//RESET $j, $j must be one again, nothing is working I have tried $j = 1;
//It's keep incrementing 1,2,3,4,5,6,7.....
}

}
$j++

Please help

    Something like this should work. Simply start at zero, increment it in beginning and reset the $j if the action occurs, the next time it loops the $j will increment again and be in zero configuration (i.e. contain value 1):

    $j = 0; 
    while($row = mysqli_fetch_array($check))
    {
        $j++;
        $value = $row['tmpi'];
        $calculate = mysqli_query($link,"SELECT * FROM tmpi_db WHERE  tmpi_id = '".value."'");
        $action = mysqli_num_rows($calculate); 
        if($j == $action)
        {
            $j = 0;
        }
    }
