How I can call $x variable of Php inside shortcode of a plugin Wordpress?

Question

$dt = date_default_timezone_set('America/New_York');
$dt = date("h:i:s");
$x = date('d-m-Y');
$d = $dt;
//echo $x." ".$d;
echo do_shortcode('[tminus t= "10-10-2015 00:00:00"]');
//echo do_shortcode('[tminus t= "'.$x.'""00:00:00"]');

I have used $x variable inside shortcode but my site goes blank, due to syntax error I know it. But how can I call variable in this shortcode please any one can tell me?

Answer 1

you could use string substitution with "..$x.." or concatenate the strings

Concatenation:

echo do_shortcode('[tminus t= "' . $x . ' 00:00:00"]');

Substitution (vars will be expanded):

echo do_shortcode("[tminus t= \"$x 00:00:00\"]");
