3,684 PointsCannot understand the while loop code.
If $player1 has an initial score of 0 and $player2 has an initial score of 5, how can the while loop make an absolute value of -5 to 5 and say that it is less than 2 and say it's true? while(abs($player1 - $player2) < 2 || ( $player1 < 11 && $player2 < 11)){ }
also how exactly do the player get a score from the rand() function? It gives a number between 0 and 1. If it's 1, player 1 gets a score and if 0 player 2?

3,684 PointsOh ok, I think I got it the second time I watched the video, lol.
The rand(0,1) means that the min and max values are inclusive. So each time the function will randomly generate either 0 or 1. Since 0 is false and 1 is true, $player1 will receive a point when 1 is generated since he is an the if code block and player 2 will receive a point when 0 is generated since he is in the else code block.
Regarding the second issue, as long as the difference between their scores is less than 2 we will continue to loop. Since Alena gave $player2 = 5 and we find the absolute value which gives 5 < 2 it evaluates to false but the other condition is still true as they are less than 11 and the loop continues to loop. I hope I got it right.
