When building URLs in code, you can use string concatenation to collect all strings:
$url = $domain.'/index.php?option='.$option.'&view='.$view.'¶m1='.$value1;
This approach is even convenient for short strings. However, it is not so convenient and intuitive if there are many parameters or need to be standardized/cleaned in the process. For example, part of the URL might contain a leading slash (the slash at the beginning of the URL fragment), and the incoming domain name of the request might also end in a slash, so we get a bad URL with a double slash somewhere in the middle ……
To standardize and unify URL retrieval tasks, Joomla provides the JoomlaUriUri class. In Joomla 1.6 and earlier, it was called JUri. This class handles URLs according to the RFC3986 standard and is responsible for parsing or assembling URLs from their various parts.
Example: Get specific parameters from URL
use Joomla\Uri\Uri; $url = 'https://web-tolk.ru/dev/biblioteki?param=value'; $uri = new Uri($url); // 此处输出'value' echo $uri->getVar('param');
You might say, yes, there is a native PHP function parse_url
... but the Uri class ensures safe operations on UTF-8 characters in URLs, including Cyrillic domain names. To avoid writing various checks yourself, you can use Joomla core functionality.
How to build the required URL in Joomla code
It’s also very simple here:
use Joomla\Uri\Uri; $uri = new Uri; $uri->setHost('web-tolk.ru'); $uri->setScheme('https'); // setPath()以前导斜杠开头 $uri->setPath('/dev/biblioteki'); // GET参数可以作为数组传递 $vars = [ 'param1' => 'value1', 'param2' => 'value2', 'param3' => 'value3', ]; $uri->setQuery($vars); // 将URL作为字符串输出 echo $uri->toString();
The hierarchical structure of the Uri class in Joomla is designed so that the getter method is located in the AbstractUri class, and the setter method is located in the Uri class. You can view the setter method in the libraries/vendor/joomla/uri/src/Uri.php file. You can view the getter method in the libraries/vendor/joomla/uri/src/AbstractUri.php file.
If you use PHPStorm, it understands Joomla completely and will tell you everything you need.
You can refer to the old documentation page, which is still applicable to a large extent and has been adapted for the use of namespaces.
Uri structure:
<code> foo://example.com:8042/over/there?name=ferret#nose \_/ \______________/\_________/ \_________/ \__/ | | | | | scheme authority path query fragment</code>

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),
