Get random array list program code in php_PHP tutorial

This article will introduce to you some commonly used PHP example programs for obtaining random arrays in arrays. I hope this method will be helpful to all my friends.

Post a piece of code to get a random array in php. Needless to say, just post the code directly. array_rand in php is very abnormal, breaking through the understanding of normal people, and is cumbersome

Example 1

The code is as follows

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; $x < count($_temp_key); $x++) { $ids[] = $_base_ids[$_temp_key[$x]]; } return $ids; }

Copy code

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"; ?>

function create_random_ids( $min,$max,$limited )

{ $_base_ids = range($min,$max);
$_temp_key = array_rand ($_base_ids,min(count($_base_ids),$limited+10)); //Splicing

$ids = array();

for ($x=0; $x < count($_temp_key); $x++) {

          $ids[] = $_base_ids[$_temp_key[$x]];

<strong>第二次得到的结果为： </strong>

}

Return $ids;

<strong>第三次得到的结果为：<br></strong> <img src="/static/imghw/default1.png" data-src="http://www.bkjia.com/uploads/allimg/131231/132F03115-2.jpg" class="lazy"   style="max-width:90%" alt="php 随机打乱一个数组的排序shuffle - 九重海 - jiuchonghai-PHP的博客" __1379995076531__="ev_6379571093">

}

$a = array(0,1,2,3,4,5,6,7,8); echo "The original order of $a is: "; foreach($a as $v) echo $v."t"; shuffle($a); echo " The scrambled order of $a is: "; foreach($a as $v) echo $v."t"; ?> The first result is: http://www.bkjia.com/PHPjc/631246.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/631246.htmlTechArticleThis article will introduce you to some commonly used PHP example programs for obtaining random arrays in arrays.
