Question

Basically what the title says. I know how to make a normal variable into a session variable ($_SESSION['var']), but not when it contains another var

This is my code:

<?php
session_start();

$_SESSION["uname"] = "Tyler";

if (isset($_SESSION["coins{$uname}"])) 
{
    echo "$_SESSION["uname"] : $_SESSION["coins{$uname}"]";
}
elseif ($_SESSION["uname"] == "LOut")
{
    $_SESSION["coins{$uname}"] = "0";
    echo "Log In";
}
else
{
    $_SESSION["coins{$uname}"] = 500;
    echo "$_SESSION["uname"] : $_SESSION["coins{$uname}"]";
}
?>

I’ve tried the following:

$_SESSION['{coins.$uname}']
$_SESSION['coins.$uname']
$_SESSION['coins.$_SESSION['uname']']

And I don’t remember if I’ve tried anything else.

Answer 1

You say that it’s not working, but you haven’t specified if setting it or echoing it is the problem: Based on your original, unedited question, there are two problems:

Setting the session variable

This should work:

$_SESSION["coins{$uname}"] = 500;

If you can’t get it to work, try breaking it down into a couple of steps.

$tempname = 'coins'.$uname;
$_SESSION[$tempname] = 500;

Now test it.

Outputting the session variable

echo $_SESSION["coins{$uname}"]; or echo $_SESSION[$tempname];

Edit

There is a syntax error in your code:

echo "$_SESSION["uname"] : $_SESSION["coins{$uname}"]";

You are closing your starting quote (“) by mistake when you try to open quotes for [“uname”]. Try:

echo "$_SESSION['uname'] : ".$_SESSION["coins{$uname}"];
