What is a 'pure function' and how to write one in PHP?
Article Introduction：Pure functions are concepts in functional programming. They can be implemented in PHP by following specific rules. The core features include: 1. No side effects, no modification of global variables, object states or performing I/O operations; 2. The same input always returns the same output, and does not rely on external data such as time and random numbers; 3. Keep simple and focused, only process inputs and return results, and do not use reference modifications or static variables to retain state. For example, sum(int$a,int$b):int is a typical pure function that only depends on parameters and has no external influence.

Which is better PHP or Laravel?
Article Introduction：PHP and Laravel are not directly comparable, because Laravel is a PHP-based framework. 1.PHP is suitable for small projects or rapid prototyping because it is simple and direct. 2. Laravel is suitable for large projects or efficient development because it provides rich functions and tools, but has a steep learning curve and may not be as good as pure PHP.

How to call a php function in html?
Article Introduction：Calling PHP functions in HTML pages requires saving the file in .php format and running in the server environment. The specific steps are as follows: 1. Change the file suffix to .php to ensure that the server can parse PHP code; 2. Use embedded PHP function calls in .php files to dynamically generate content; 3. You can output HTML elements, such as buttons or menus through functions, to achieve dynamic page control; 4. Pay attention to ensuring that the server supports PHP, correctly wraps PHP code, and avoid running PHP directly in pure HTML files.

How does PHP integrate with message queuing systems (e.g., RabbitMQ, Kafka)?
Article Introduction：PHP integrates with RabbitMQ and Kafka and other message queue systems through dedicated libraries and extensions to realize message production and consumption. 1. Use the php-amqplib library or amqp extension to connect to RabbitMQ, declare queues and publish or consume messages; 2. Integrate PHP with Kafka through the php-rdkafka library, and configure producers or consumers to send or read messages; 3. When processing fails, make sure that messages are only confirmed after successful processing, and use dead letter queues, retry mechanisms and logging to avoid infinite loops; 4. In RabbitMQ, ack/nack can be used to control messages, and Kafka needs to manually submit offsets; 5. In terms of performance, it is recommended to use CLI scripts to run consumers.

Your First PHP Code
Article Introduction：Quick view of PHP core concepts
Server-side language: PHP code is executed on the server side, not on the browser side, which means that the browser only receives standard HTML, avoids browser compatibility issues and reduces client load.
Dynamic web page generation: PHP embeds HTML, giving web pages stronger dynamic interaction capabilities, surpassing the static rendering of pure HTML.
Statements and functions: A PHP script consists of a series of statements ending with a semicolon. Functions can be called and parameters can be passed in to achieve diversified functions.
Delimiter: marks the start and end of the PHP code block, and the server parses the code in this area and converts it into HTML.
Multilingual collaboration: PHP can be combined with H

how to deep copy a php array
Article Introduction：There are three ways to implement deep copy of arrays in PHP: First, use unserialize and serialize to disconnect references by serializing and deserializing, which is suitable for ordinary and nested arrays; second, object arrays combine clone and recursive functions to flexibly process mixed types but ensure that the class supports correct cloning; third, json_encode and json_decode are suitable for pure scalar data, with simple writing but no resources or special objects.

How to sort php array by value
Article Introduction：In PHP, sorting arrays by value requires selecting different functions according to your needs. 1. Use asort() (ascending order) and arsort() (descending order) to preserve key-value associations, which are suitable for associative arrays; 2. Use sort() (ascending order) and rsort() (descending order) to sort only values ??and reset keys, which are suitable for pure numeric arrays; 3. Use usort() to customize sorting rules, which are suitable for complex structures such as objects or nested arrays, but do not retain the original keys.

Beyond `if-else`: Exploring PHP's Alternative Control Structures
Article Introduction：The alternative control structure of PHP uses colons and keywords such as endif and endfor instead of curly braces, which can improve the readability of mixed HTML. 1. If-elseif-else starts with a colon and ends with an endif, making the condition block clearer; 2. Foreach is easier to identify in the template loop, and endforeach clearly indicates the end of the loop; 3. For and while are rarely used, they are also supported. This syntax has obvious advantages in view files: reduce syntax errors, enhance readability, and is similar to HTML tag structure. But curly braces should continue to be used in pure PHP files to avoid confusion. Therefore, alternative syntax is recommended in templates that mix PHP and HTML to improve code maintainability.

PHP string to lowercase
Article Introduction：PHP provides a variety of string to lowercase methods, suitable for different scenarios. 1. The strtolower() function is suitable for most English scenarios, converting uppercase letters to lowercase, but poor support for non-ASCII characters; 2. mb_strtolower() supports multilingual, more accurate processing of Unicode encoding, and suitable for special characters such as French and German; 3. You can clean spaces or symbols in combination with trim() or preg_replace() to generate slug format; 4. Use LOWER() to achieve fuzzy matching in database queries, pay attention to whether the index is case sensitive. For pure English systems, strtolower() is used, while for internationalization requirements, mb_strtolower() is used.
