Several ways to randomly sort php arrays_PHP tutorial

In PHP, if we want to randomly sort the array, we only need to use the shuffle function, but shuffle can only use one-dimensional arrays. Below, I will introduce you to several array sorting methods.

You can use the shuffle function in PHP to implement random sorting of arrays.

The code is as follows

代码如下	复制代码
$test=array(); $test[]=array( 'title'=>'Q1.较为科学的安全期算法是什么？',         ); $test[]=array(         'title'=>'Q2.较为科学的安全期算法是什么？',         ); $test[]=array(         'title'=>'Q3.较为科学的安全期算法是什么？',         ); $test[]=array(         'title'=>'Q4.较为科学的安全期算法是什么？',         ); //随机排序 shuffle($test); print_r($test); ?>

Copy code

$test=array();

$test[]=array(

'title'=>'Q1. What is the more scientific safe period algorithm? ', ); $test[]=array( 'title'=>'Q2. What is the more scientific safe period algorithm? ', ); $test[]=array( 'title'=>'Q3. What is the more scientific safe period algorithm? ', ); $test[]=array( 'title'=>'Q4. What is the more scientific safe period algorithm? ', ); //Randomly sort shuffle($test); print_r($test); ?>
