I try to do a redirection with header like this:
header('location:perfil.php?CodUsua=<?php echo $_SESSION['CodUsua']; ?>');
I receive the following error:
Parse error: syntax error, unexpected 'CodUsua' (T_STRING), expecting ',' or ')'
What would be the correct syntax?
If you're doing header , that means you're already in PHP. You do not have to reopen <?php or write with echo . That's why you get the syntax error.
To fix it: simply concatenate the session variable to the string you already have using the operator . :
header('location:perfil.php?CodUsua=' . $_SESSION['CodUsua']);
