Variable in Header

$c = 'Hello.php';

header('Refresh: 2; URL= $c ');

This i开发者_JAVA技巧s not working. Is this legal?

It is legal but you will need to use "" as string delimiters

$c = 'Hello.php';

header("Refresh: 2; URL= $c ");

Also see: http://nl.php.net/manual/en/language.types.string.php on single and double quoted strings

Variable interpolation only occurs in double quoted (") strings.

$c = 'Hello.php';

header("Refresh: 2; URL= $c");
