using variables inside header function

[amrigo]

I am getting an error message using header, to pass a get variable as php variable
using both ways below:

header( Location: file.php?variable=<?php echo $variable;?>);
header( Location: file.php?variable=$variable);

Can i use a variable inside header?

Thank´s in advance!!-

try

<?php
header("Location: file.php?variable=" . $variable);
?>

thanks´a lot but how can i deal with the headers already sent problem ?

I get this error:

Cannot modify header information - headers already sent by ....

I may be too late in answering this, but try removing everything before the <?php tag.

If there is even a space, you will get an error.
