How to pass variables in PHP

Question

I'm not sure how to pass the value of $tid to another php file. Well, I do know how but the thing is I want to have the button store the current $tid since it's gonna change after the next loop. If I use sessions and just call it from another file, $tid's value will be that of the last iteration.

    $select = mysqli_query($conn, "SELECT  Sport, TeamID, TeamAcadYear FROM team");

    echo "<html> <body> <table align='center'>";

    while($row = mysqli_fetch_array($select)){
        $sportName = $row['Sport']; 
        $tay = $row['TeamAcadYear'];
        $tid = $row['TeamID'];

        echo " <tr> <td> <button type='button'> $sportName" ." " ."$tay </button> </td> </tr>";
    } 
    echo "</table> </body> </html>";

@JoeKeene Im going to use it for a mysql statement. ill use the TeamID (tid) thats passed to select a team that has that ID and then display the info of that team — Louise, May 16 '17 at 15:01

@mxr7350 I know how to use sessions, cookies, etc. The problem is that as the while loop iterates, the tid changes. What happens if there are three rows retrieved from the select statement but the user clicks the first button. How can I get the tid of that row and pass it to another file? — Louise, May 16 '17 at 15:13
@mxr7350 And how do you access an HTML tags `id` value in PHP? Do please enlighten me — RiggsFolly, May 16 '17 at 15:23

You can use $_GET.

For example:

Page 1:

<a href='page2.php?id=$id'><button type='button'> $sportName" ." " ."$tay </button></a>

Page 2:

To get the ID:

$idFromPage1 = $_GET['id'];

echo $idFromPage1; // Your ID from page 1 will be displayed

I can't think of a single situation where `$_GET` is the best way of passing data between pages. – Martin May 16 '17 at 15:54

You're correct $_SESSION would be the ideal way, another way is to use GET or POST to send the value to another page. Could you name the $_SESSION vars like currentTid and previousTid etc?
