To tell you the truth, I am also a fan of double-color balls. I often buy them, but I have never won the first prize, haha.
Here are two methods of randomly generating Welfare Lottery numbers using PHP for your reference. In the new year, I wish you all a big win and a fortune.

Method 1

Copy code The code is as follows:

/*
Randomly generate welfare lottery numbers
*/
$red = array(1,2,3,4,5,6,7,8,9,10,11,12, 13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33);
$blue = array (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16);
for ($i=0;$i<6;$ i++){
$index = rand(0,32-$i);
$redBall[]= $red[$index];
unset($red[$index]);
for($k=$index;$k $red[$k]=$red[$k+1];
}
}
asort($redBall);
?>
foreach($redBall as $v){
echo $v." ";
}
?>


echo $blue[rand( 0,15)];
?>


Method 2
Copy Code The code is as follows:

/*
Randomly generate welfare lottery double color ball numbers
*/
echo "
";
echo "

";
$red1=range(1,33);
$blue1=mt_rand(1,6);
$sc1=array_rand($red1, 6);
?>


< ?php
foreach($sc1 as $v){
echo "$v ";
}
?>


echo "$blue1";
?>


The former method is relatively troublesome. Friends in need may wish to refer to the second method.
