<?
  $array=array('1','2','3','4','5','6','7','8');
  $number=array_rand($array,'1');
  $count=array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","23","24","25","26","27","28","29","30","31","32","33","34","35","36","37","38","39","40","41","42","43","44","45","46","47","48","49","50","51","52","53","54","55","56","57","58","59","60","61","62","63","64","65","66","67","68","69","70","71","72","73","74","75","76","77","78","79","80","81","82","83","84","85","86","87","88","89","90","91","92","93","94","95","96","97","98","99","100");

Answer 10

楼上的小帅锅，你可以注意一下range

Answer 11

呵呵 多谢指教
刚才贴错了 贴了一个测试页面<?
  $array=array('1','2','3','4','5','6','7','8');
  $number=array_rand($array,'1');
  $a=$array[$number];
  $count = range(1,100);
  $no='22';
  $number1=array_rand($count,$a);
  foreach($number1 as $val)
  {
   echo$val;
   echo"<br>";
  }
  echo $no;
  echo"<br>";
  $b=$a+1;
  echo  $b."次取得".$no;
 ?>
