It is completely randomly designed using PHP. Each time it is refreshed, there will be different lucky numbers. Give it a try and don’t forget neo when you get rich~~~
for ($n=1;$n<=5;$n++ ) {
echo "No.".$n."Note";
$string="";//Initialization string
for ($i=1;$i<=7;$i++) {
mt_srand((double )microtime()*1000000);//Add the time factor to use the millionth of a second during execution as the random number seed
$random=mt_rand(1,30);//Generate a random number between 1-30
if (eregi($random,$string)){//Check whether this number already exists
$i--;
continue;//Jump out of the loop and return to the starting point of judgment.
}
else{
$string=$string.",".$random;
echo $random," ";}
}
echo "
";
}
?>
