To master the sorting of PHP arrays, you must first understand its core behavior and function selection logic: 1. Sort by value and re-index numeric keys, use sort() or rsort(); 2. Sort by value but keep the keys (applicable to associative arrays), use asort() or arsort(); 3. Sort by keys, use ksort() or krsort(); 4. When customizing the sort logic, use usort() (no key reserved) or uasort() (preserved key) with callback function; 5. Use sort flags such as SORT_NUMERIC, SORT_STRING, SORT_NATURAL to control the comparison method; 6. Pay attention to common traps: sort() series functions return tru

PHP can automatically classify customer problems by integrating AI models and improve customer service efficiency; 2. When choosing AI services, cloud APIs (such as OpenAI, GoogleCloud) are preferred to lower the threshold, and use self-built Python model services for high privacy or customization needs; 3. PHP asynchronously calls AI models through HTTP, combines message queues (such as Redis/RabbitMQ) to avoid blockage, and do text preprocessing, result parsing and error retry; 4. Classification results are used to automatically route work orders, prioritize, knowledge base recommendation and automatic reply, and ultimately drive service optimization and product improvement.

This article details how to efficiently classify and reorganize string elements from different arrays in PHP. By merging the original array and then using the strpos function to detect whether a string contains a specific character (such as the letter "u"), the elements that meet the conditions are finally classified into a new array and elements that do not meet the conditions are classified into another new array. This method avoids complex element exchange logic and improves code clarity and execution efficiency.

Variables defined in PHP functions are only accessible inside their functions, which is the basic rule for the scope of variables of PHP functions. Local scope means that variables can only be used within the function that declares it. To use this value outside the function, it needs to be returned through return; global variables need to be accessed in the function using the global keyword or $GLOBALS hyperglobal array; static variables are declared through static, and their value can be maintained between multiple function calls.
