I have a two-dimensional array with a fixed number of items, and I want to disrupt the order of the array while keeping the key values unchanged. My array is as follows
<code>$result = ['12'=>[], '14'=>[], '15'=>[], '17'=>[], '23'=>[]]</code>
My array always only has 5 pieces of data. The main reason is that the key values in it are not fixed. Every time the key values are taken out, they are in order from small to large. But now I need to disrupt this order and return to the page while keeping the key values unchanged. I have tried using the shuffle
function, which directly deletes the key values of the array, which is not the result I want.
Dear masters, can you give me a reference method? Thank you

The
shuffle
function will reset the key values of the array. Two-dimensional arrays require some logical processing. Reference is as follows
<code>function arrayOrderBy($array=[]){ //获取键值 $keys = array_keys($array); //打乱键值 shuffle($keys); $random = []; //数组重组 foreach($keys as $key){ $random[$key] = $array[$key]; } return $random; }</code>
Try it locally, I hope it helps you

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
