本文章来给大家介绍一些常用的php获取数组中随机数组的一些实例程序,希望此方法对各位朋友有所帮助哦。

贴一段代码,在php中获取随机数组 不用多说,直接贴代码,php中的array_rand很变态,突破了正常人的理解,繁琐

例1

 代码如下 复制代码

function create_random_ids( $min,$max,$limited )
{
    $_base_ids = range($min,$max);
    $_temp_key = array_rand ($_base_ids,min(count($_base_ids),$limited+10));
    //拼接
    $ids = array();
    for ($x=0; $x         $ids[] = $_base_ids[$_temp_key[$x]];
    }
    return $ids;
}

例2

 代码如下 复制代码

$a = array(0,1,2,3,4,5,6,7,8);
echo "$a原来的顺序为:


";
foreach($a as $v)
 echo $v."t";
shuffle($a);
echo "
$a被打乱后的顺序为:
";
foreach($a as $v)
 echo $v."t";
?>

第一次得到的结果为:

Copy after login
Copy after login
 
Copy after login
<strong>第二次得到的结果为: </strong>
Copy after login
Copy after login
Copy after login
<strong>第三次得到的结果为:<br></strong> 
Copy after login
