how to put php variable in header location?

Question

my code is

<?php 
if(empty($_SESSION["adm_no"]))
{
    header("Location:<?php echo $homepage; ?jaxmas=wHgfghks^^%&fnjfskjdfb");
    
}
?>

I want to pass url through variable, but I am unable to get values from that variable.

Answer 1

You are putting php tags twice. Try this:

<?php 
if(empty($_SESSION["adm_no"]))
{
    header("Location:".$homepage."?jaxmas=wHgfghks^^%&fnjfskjdfb");
}
?>
<?php 
if(empty($_SESSION["adm_no"]))
{
    header("Location:".$homepage."?jaxmas=wHgfghks^^%&fnjfskjdfb");
}
?>

Answer 2

You don't need to open another php opening tags inside the opened one.

<?php 
  session_start();
if(empty($_SESSION["adm_no"]))
{
    header("Location:$homepage?jaxmas=wHgfghks^^%&fnjfskjdfb");

}
?>
