How should I echo a PHP string variable that contains special characters?

Question

I\'m trying to populate a form with some data that contains special characters (e.g. single quote, double quote,<,>,?,\",\"\".~,,!@#$%^&*()_+}{\":?<<>,./;\'[.]

Answer 1

whats wrong with using a constant ?

,?,","".~,,!@#$%^&*()_+}{":?<<>,./;');
$foo2="'[.]";
echo constant('foo').$foo2;
?>

you need to put the '[.]' into a variable, as a constant will break on a ' (single quote).
