I would like to use a function to check to see if a session variable
is set and return the session variable if it is set, and return blank
if not. Something like
function set_var($var)
{
echo "var = $var \n";
if (isset($_SESSION['$var']))
{
return $_SESSION['$var'];
}
else
{
return "";
}
}
And I would call the function with set_var($name) or set_var($phone).
The problem is getting the function to use $var as a variable name,
rather than a value. What am I missing, please?
