The spread operator of PHP8.1 can be used to expand iterable objects in an array. 1. It can simplify the combination and merge of numbers, and replace array_merge with [...$array1,...$array2]; 2. It can directly expand the Traversable object and generator without the need for iterator_to_array(); 3. It supports passing variable parameters in function calls; it should be noted that it is only applicable to iterable objects. Non-iteration types will throw errors, numeric keys will be re-indexed, and the value after the string key overwrites the previous value. Therefore, it is recommended to use in PHP8.1 to improve code readability.

To debug RESTAPI requests, you must first confirm whether the request structure is correct, including URL, HTTP methods, Headers and Body. 1. Check whether the URL is complete and accurate to avoid 404 due to spelling errors; 2. Use the correct HTTP method to prevent 405 from returning due to mismatch of methods; 3. Check the Headers content, such as Content-Type and Authorization; 4. Ensure that the Body data format is consistent with the interface requirements. Then use the debugging tool to analyze the request details, such as the browser developer tool to view the network panel, or the Postman and curl manual test interfaces, and use the packet capture tool to analyze the HTTPS request content if necessary. Then judge the problem based on the response status code

To update Linux system packages, you must first run sudoaptupdate to refresh the source list, otherwise it may cause the installation to fail or the version is too old. 1. Update the software source: execute sudoaptupdate; 2. Upgrade the software package: It is recommended to use sudoaptfull-upgrade to completely upgrade and install new dependencies, but be careful to uninstall conflict packages; 3. Clean useless packages: Use sudoaptautoremove and sudoaptclean to release disk space; in addition, when encountering GPG errors, you should check the key. If you connect to a connection problem, you can try to replace the domestic mirror source. Usually, you can use aptlist-upgradable to view the upgradeable package, or complete it at one time with the command chain.

DOM parsing is suitable for small files. It loads the entire XML into memory to build a tree structure, supports random access and modification, but it consumes a lot of memory and is prone to trigger OOM; 2. SAX parsing is event-driven streaming processing, with low memory usage and fast parsing speed. It is suitable for large file read-only scenarios, but can only be read in sequence and has complex programming model; 3. StAX parsing is a pull streaming processing, which is memory friendly and flexible in control, has good performance and ease of use, supports write operations, and is recommended for medium and large file processing. StAX is preferred for new projects, and DOM is used when small files are required and modification is required. SAX is available under extreme resource limitations.

WordPress insufficient memory error can be resolved by adjusting memory limits. 1. Modify the wp-config.php file and add define ('WP_MEMORY_LIMIT','256M') to increase the memory limit. Ordinary sites can be set to 128M or 256M, and e-commerce or multiple author sites can be 512M; 2. If it does not take effect, it may be a server restriction, you can try to edit php.ini to set memory_limit=256M or contact the host manufacturer for assistance; 3. Use plug-ins such as WPMemoryUsage or HealthCheck&Troubleshooting to view the current memory usage and assist in troubleshooting. Improve memory

The key to creating stored procedures in Navicat is to understand the database type and its syntax differences. The following are the specific steps: 1. Preparation: Confirm the connected database type (such as MySQL, PostgreSQL or SQLServer) because the stored procedures of different databases are different syntax; 2. Open the "Store Procedure" panel and create a new one: Enter the stored procedure management interface through the Navicat interface, right-click to select "New stored procedure", enter the name and use the template structure; 3. Write SQL logic: Define parameters and statements, such as adding IN parameters to MySQL and writing query logic in the BEGIN...END block, pay attention to using DELIMITER to set the ending character; 4.

PHP's garbage collection handles circular references through reference counting and periodic loop collectors. First, the reference count releases memory immediately when the variable has no reference, but cannot handle the situation where mutual references between objects are referenced. For example, $a and $b refer to each other to form a loop. Even if the external reference is set to null, the reference count is still not zero. For this reason, PHP introduced a circular garbage collector, 1. The collector runs periodically based on heuristic rules and does not trigger immediately; 2. Identify possible circular garbage through the marking stage; 3. Release memory after confirming that it is unreachable in the clearing stage; 4. Collect can be manually triggered through gc_collect_cycles(); 5. Gc_disable() and gc_enable() can be used to control the collector switch; 6

switch(true) can be used in PHP for structured condition judgment, but does not naturally support strict type checking; 2. The ===, is_* functions or instanceof must be used to ensure strict comparison; 3. The order of conditions affects the results, and specific conditions must be placed first; 4. Avoid using them in simple value matching or performance-sensitive scenarios; 5. The readability of complex logic can be improved when used correctly, but abuse will reduce the clarity of code. Therefore, the correctness and maintainability of the code should be given priority rather than the pursuit of syntax techniques.

Data import errors are common and can be solved, the key is to troubleshoot according to the steps. 1. Check whether the file format is consistent with the system requirements, such as the line breaks or date formats in CSV do not match. 2. Ensure that the field types match. If the number field does not contain strings, pay attention to the identification differences between different time formats. 3. Verify data integrity, check the uniqueness of primary keys and missing key fields in advance, and use tools to count empty values. 4. Handle encoding and special character issues, clearly specify the encoding format, and check invisible characters and illegal escape characters. 5. Use logs and error information to locate problems, enable detailed log mode and correct the original data details errors according to the prompts.
