PHP method example code to obtain a random array list

This article mainly introduces the method of php to obtain a random array list, involving the application of random numbers to array traversal, which is of great practical value. Friends who need it can refer to it.

The example in this article describes the example program of obtaining a random array in an array in PHP, and shares it with you for your reference. The specific implementation method is as follows:

Needless to say, just paste the code directly. array_rand in php is very abnormal, breaks through the understanding of normal people, and is very complicated
Example 1:

The code is as follows:

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;
}

Example 2:

The code is as follows:

<?php 
$a = array(0,1,2,3,4,5,6,7,8);
echo "$a原来的顺序为：<hr/>";
foreach($a as $v)
 echo $v."t";
shuffle($a);
echo "<br/>$a被打乱后的顺序为：<hr/>";
foreach($a as $v)
 echo $v."t";
?>

The first result is:

The result obtained for the second time is:

The result obtained for the third time is:
