If I have 30 session variables and I want to do an if statement to only 10 of them.
if (empty($_SESSION['XYZ'])) {
$_SESSION['XYZ'] = 0;
}
what should I do? Do I call an if statement after every session variables that i needed for?

Consider putting the names of the keys in an array and then looping through with foreach.
$keys = array('x','y','z');
foreach ($keys as $key)
{
if (empty($_SESSION[$key])
{
// do stuff
}
}
An advantage is you can quickly add or remove keys to check.

$vars = array('XYZ','ABC','DEF');
foreach($vars as $i){
if(empty($_SESSION[$i])) $_SESSION[$i] = 0;
}

I like how we have the same answer 4 times now, and counting!

If they are in series, that is, from 0 to 29 then you can use a loop to traverse them!

Something like so?
$keys = array("A", "B", "C", "D", "E", "F");
foreach ($keys as $key) {
if (empty($_SESSION[$key])) {
$_SESSION[$key] = 0;
}
}

You could list the keys you want to zero-out in an array and set them as follows:
$keys = array('XYZ','FOO','BAR');
foreach ($keys as $key) {
if (empty($_SESSION[$key])) {
$_SESSION[$key] = 0;
}
}
