if multiple random numbers are all equal return true

if multiple random numbers are all equal return true

Im working on some random generator, and it's something like roll a dices,
if all dices are returning same numbers than you won a game if not than
you try again.
To get six dices i used mt_rand function and for every dice separately, so
i have this:
$first = mt_rand(1,6);
$second = mt_rand(1,6);
$third = mt_rand(1,6);
$fourth = mt_rand(1,6);
$fifth = mt_rand(1,6);
$sixth = mt_rand(1,6);
But i don't know how to return if operand for multiple random generated
numbers.
If i would use like 2 dices i would just use
if ( $first === $second )
that would return true if first and second dices, both have returned number 2
But how do i use it if i want to echo true if all 6 dices to return number
2 ?
