php - URL Redirection, with target location stored in a variable -


i have problem redirecting page, when target location stored in variable.

this code works:

header('location:demo.php');

but code doesn't work:

$ss='demo.php'; header('location:$ss');

why? thank help.

you have use double quotes here. php parse text inside double quotes.

if type example

echo '$text\n';

it not output variables content, nor newline. corect be:

echo "$test\n";
