php获取随机数组列表的方法,php获取数组
本文实例讲述了php获取数组中随机数组的实例程序,分享给大家供大家参考。具体实现方法如下:
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,非常繁琐
例1:
复制代码 代码如下:
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:
复制代码 代码如下:
$a = array(0,1,2,3,4,5,6,7,8);
echo "$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:
第二次得到的结果为:
第三次得到的结果为:
希望本文所述对大家的php程序设计有所帮助。
